If a response file in construct `@file` was specified by relative name,
constructs `@file` nested within it were resolved incorrectly if the
flag RelativeNames in call to ExpandResponseFile was set to true.
This feature is used in configuration files, tests for it are in
respective change (see D24933).

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.

subcommands
This commit fixes a bug where the help output doesn't display subcommands when
a tool has less than 3 subcommands.
This change doesn't include a corresponding unittest as there is no viable way
to provide a unittest for it.

Previously we would print
USAGE: <exe> [subcommand] [options]
Even if no subcommands were present. This changes the output
format to only print "[subcommand]" if there is at least one
subcommand.

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.

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.

Summary:
As per the discussion on LLVM-dev this patch proposes removing LLVM_ENABLE_TIMESTAMPS.
The only complicated bit of this patch is the Windows support. On windows we used to log an error if /INCREMENTAL was passed to the linker when timestamps were disabled.
With this change since timestamps in code are always disabled we will always compile on windows with /Brepro unless /INCREMENTAL is specified, and we will log a warning when /INCREMENTAL is specified to notify the user that the build will be non-deterministic.

In gcc, \ escapes every character in response files. It is true that this makes
it harder to mention Windows files in rsp files, but not doing this means clang
disagrees with gcc, and also disagrees with the shell (on non-Windows) which
rsp file quoting is supposed to match. clang isn't free to choose what to do
here.
In general, the idea for response files is to take bits of your command line
and write them to a file unchanged, and have things work the same way. Since
the command line would've been interpreted by the shell, things in the rsp file
need to be subject to the same shell quoting rules.
People who want to put Windows-style paths in their response files either need
to do any of:
* escape their backslashes
* or use clang-cl which uses cl.exe/cmd.exe quoting rules
* pass --rsp-quoting=windows to clang to tell it to use
cl.exe/cmd.exe quoting rules for response files.
Fixes PR27464.

Added new string conversion wrappers that convert between `std::string` (of UTF-8 bytes) and `std::wstring`, which is particularly useful for Win32 interop. Also fixed a missing string conversion for `getenv` on Win32, using these new wrappers.
The motivation behind this is to provide the support functions required for LLDB to work properly on Windows with non-ASCII data; however, the functions are not LLDB specific.

StringSaver now always saves to a BumpPtrAllocator.
The only reason for having the virtual saveImpl is so lld can have a
thread safe version.
The reason for the distinct BumpPtrStringSaver class is to avoid the
virtual destructor.

Summary:
The primary goal of this patch is to remove the need for MarkOptionsChanged(). That goal is accomplished by having addOption and removeOption properly sort the options.
This patch puts the new add and remove functionality on a CommandLineParser class that is a placeholder. Some of the functionality in this class will need to be merged into the OptionRegistry, and other bits can hopefully be in a better abstraction.
This patch also removes the RegisteredOptionList global, and the need for cl::Option objects to be linked list nodes.
The changes in CommandLineTest.cpp are required because these changes shift when we validate that options are not duplicated. Before this change duplicate options were only found during certain cl API calls (like cl::ParseCommandLine). With this change duplicate options are found during option construction.
