94750391d9 Revert [CommandLine] Remove OptionCategory and SubCommand caches from the Option class.
This reverts r364134 (git commit a5b83bc9e3b8e8945b55068c762bd6c73621a4b0)

Caused errors in the asan bot, so the GeneralCategory global needs to
be changed to ManagedStatic.

4130c915bb [CommandLine] Remove OptionCategory and SubCommand caches from the Option class.
Summary:
This change processes `OptionCategory`s and `SubCommand`s as they
 are seen instead of caching them in the Option class and processing
them later.  Doing so simplifies the work needed to be done by the Global
parser and significantly reduces the size of the Option class to a mere 64
bytes.

Removing  the `OptionCategory` cache saved 24 bytes, and removing
the `SubCommand` cache saved an additional 48 bytes, for a total of a
72 byte reduction.

d72e12d3db [CommandLine] Reduce size of Option class
Summary:
Reduce size of Option class from 184 bytes to 136 bytes by
placing more member variables in Bit Field (16 bytes), and
reducing the initial sizes of Categories and Subs to 1 (32 bytes).

Saves about 48k for bin/opt.

541e19ce1b [CommandLine] Add long option flag for cl::ParseCommandLineOptions . Part 5 of 5
Summary:
If passed, the long option flag makes the CommandLine parser
mimic the behavior or GNU getopt_long.  Short options are a single
character prefixed by a single dash, and long options are multiple
characters prefixed by a double dash.

This patch was motivated by the discussion in the following thread:

b5f456a009 [llvm] Revert r231274: "Devirtualize ~parser<T> by making it protected in base classes and making derived classes final"
Summary: This patch was previously applied in r231221, and reverted in
r231254 because it broke self-hosting.  It was subsequently fixed and
reapplied in r231274.  Unfortunately, making the `parser<T>` classes
final prevents inheritance which makes it impossible to implement
custom parsers.

Reverting r231221 restores the ability to customize parsers.

6b547686c5 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

9897943c6c [CommandLine] Error message for incorrect PositionalEatArgs usage
Summary:
bugpoint has several options specified as `PositionalEatArgs` to pass
options through to the underlying tool, e.g. `-tool-args`. The `-help`
message suggests the usage is: `-tool-args=<string>`. However, this is
misleading, because that's not how these arguments work. Rather than taking
a value, the option consumes all positional arguments until the next
recognized option (or all arguments if `--` is specified at some point).
To make this slightly clearer, instead print the help as:
```
  -tool-args <string>...                            - <tool arguments>...
```
Additionally, add an error if the user attempts to use a `PositionalEatArgs`
argument with a value, instead of silently ignoring it. Example:
```
./bin/bugpoint -tool-args=-mpcu=skylake-avx512
bugpoint: for the -tool-args option: This argument does not take a value.
    Instead, it consumes any positional arguments until the next recognized option.
```

Add a raw_ostream& parameter to the function pointer type used for
VersionPrinter, and while doing so, introduce a typedef for convenience.

Note that VersionPrinter::print() will still default to using outs(),
the clang part will necessarily go into a separate review.

e3e43d9d57 Sort the remaining #include lines in include/... and lib/....
I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.

I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.

This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.

Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

ad47702c6d Add initial support for debug counting
Summary:

We have support for bisection, and bugpoint can reduce testcases
often to a single pass. But that doesn't help reduce it to a single
transform by a single pass.  Which debug counting lets us do.

Debug counting lets you instrument a pass so that it only executes a
certain thing (rwhatever you want) after skipping it a certain time of
times, and then only does a certain number of executions before saying
"skip" again.

To make it concrete, for predicateinfo, if i instrument use renaming,
i can make it so it skips renaming the first N uses, renames the next
N, and then skips the rest.

This lets you narrow down a miscompilation to, often, a single
transformation, and then also debug it (by using the same command line
parameters).

038b68a6a3 Allow resolving response file names relative to including file
If a response file included by construct @file itself includes a response file
and that file is specified by relative file name, current behavior is to resolve
the name relative to the current working directory. The change adds additional
flag to ExpandResponseFiles that may be used to resolve nested response file
names relative to including file. With the new mode a set of related response
files may be kept together and reference each other with short position
independent names.

3ffe113e11 Turn cl::values() (for enum) from a vararg function to using C++ variadic template
The core of the change is supposed to be NFC, however it also fixes
what I believe was an undefined behavior when calling:

 va_start(ValueArgs, Desc);

with Desc being a StringRef.

f6b865d41a [Support][CommandLine] Add cl::getRegisteredSubcommands()
This should allow users of the library to get a range to iterate through
all the subcommands that are registered to the global parser. This
allows users to define subcommands in libraries that self-register to
have dispatch done at a different stage (like main). It allows for
writing code like the following:

    for (auto *S : cl::getRegisteredSubcommands()) {
      if (*S) {
	// Dispatch on S->getName().
      }
    }

This change also contains tests that show this usage pattern.

eb2c1ebbb2 Resubmit "Update llvm command line parser to support subcommands."
This fixes an issue where occurrence counts would be unexpectedly
reset when parsing different parts of a command line multiple
times.

**ORIGINAL COMMIT MESSAGE**

This allows command line tools to use syntaxes like the following:

      llvm-foo.exe command1 -o1 -o2
      llvm-foo.exe command2 -p1 -p2

Where command1 and command2 contain completely different sets of
valid options.  This is backwards compatible with previous uses
of llvm cl which did not support subcommands, as any option
which specifies no optional subcommand (e.g. all existing
code) goes into a special "top level" subcommand that expects
dashed options to appear immediately after the program name.
For example, code which is subcommand unaware would generate
a command line such as the following, where no subcommand
is specified:

      llvm-foo.exe -q1 -q2

The top level subcommand can co-exist with actual subcommands,
as it is implemented as an actual subcommand which is searched
if no explicit subcommand is specified.  So llvm-foo.exe as
specified above could be written so as to support all three
aforementioned command lines simultaneously.

There is one additional "special" subcommand called AllSubCommands,
which can be used to inject an option into every subcommand.
This is useful to support things like help, so that commands
such as:

      llvm-foo.exe --help
      llvm-foo.exe command1 --help
      llvm-foo.exe command2 --help

All work and display the help for the selected subcommand
without having to explicitly go and write code to handle each
one separately.

This patch is submitted without an example of anything actually
using subcommands, but a followup patch will convert the
llvm-pdbdump tool to use subcommands.
