Summary:
`ArgumentError` is not defined by the Python standard library.
Executing this line of code would throw a exception, but not the
intended one. It would throw a `NameError` exception, since `ArgumentError`
is undefined.
Use `ValueError` instead, which is defined by the Python standard
library.

Summary:
Semicolons aren't necessary as statement terminators in Python, and
each of these uses are superfluous as they appear at the end of a line.
The convention is to not use semicolons where not needed, so remove them.

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.

This is a new tool built on top of the new YAML ouput generated from
optimization remarks. It produces HTML for easy navigation and
visualization.
The tool assumes that hotness information for the remarks is available
(the YAML file was produced with PGO). It uses hotness to list the
remarks prioritized by the hotness on the index page. Clicking the
source location of the remark in the list takes you the source where the
remarks are rendedered inline in the source.
For now, the tool is meant as prototype.
It's written in Python. It uses PyYAML to parse the input.

Summary:
optparse is deprecated in Python 2.7, which is the minimum version of
Python required to run the LLVM test suite. Replace its usage in lit
with argparse, optparse's 2.7 replacement module.
argparse has several benefits over optparse, but this commit does not
make use of those benefits yet. Instead, it simply uses the new API,
and attempts to keep the number of changes to a minimum.
Confirmed that lit's test suite, as well as LLVM's regression test suite,
still pass with these changes.

Summary:
lit's `OneCommandFileTest` class implements an abstract method that
raises if called. However, it raises by referencing an undefined
symbol. Instead, raise explicitly by throwing a `NotImplementedError`.
This is clearer, and appeases Python linters.

Summary:
In Python, `None` is a singleton, so checking whether a variable is
`None` may be done with `is` or `is not`. This has a slight advantage
over equiality comparisons `== None` and `!= None`, since `__eq__` may
be overridden in Python to produce sometimes unexpected results.
Using `is None` and `is not None` is also recommended practice in
https://www.python.org/dev/peps/pep-0008:
> Comparisons to singletons like `None` should always be done with `is` or
> `is not`, never the equality operators.

Add two options to the code coverage artifact prep script:
* --use-existing-profdata: Use an existing indexed profile instead of
merging the same profiles again.
* --restrict: Restrict the coverage reporting to the given list of
source directories.
With this in place, we can teach the coverage bot how to prepare
separate reports for each of the llvm tools.

Previously, gtest/gtest_main were not exported via cmake. The intention here was
to ensure that users whom are linking against the LLVM install tree would not
get the gtest/gtest_main targets. This prevents downstream projects that link
against the LLVM build tree (i.e. Swift) from getting this dependency
information in their cmake builds. Without such dependency information, linker
issues can result on linux due to LLVMSupport being put before gtest on the
linker command line.
This commit preserves behavior that we want for the install tree, while adding
support for the build tree by:
1. The special casing for gtest/gtest_main in the add_llvm_library code is
removed in favor of a flag called "BUILDTREE_ONLY". If this is set, then the
library is communicating that it is only meant to be exported into the build
tree and is not meant to be installed or exported via the install tree. This
part is just a tweak to remove the special case, the underlying code is the
same.
2. The cmake code that exports cmake targets for the build tree has special code
to import an additional targets file called
LLVMBuildTreeOnlyExports.cmake. Additionally the extra targets are added to the
LLVMConfig.cmake's LLVM_EXPORTED_TARGETS variable. In contrast, the
"installation" cmake file uses the normal LLVM_EXPORTS_TARGETS as before and
does not include the extra exports file. This is implemented by
defining/undefining variables when performing a configure of the build/install
tree LLVMConfig.cmake files.

Summary:
This allows specifying instructions that are available only in specific assembler variant. If AsmVariantName is specified then instruction will be presented only in MatchTable for this variant. If not specified then assembler variants will be determined based on AsmString.
Also this allows splitting assembler match tables in same way as it is done in dissasembler.

Do this by creating a temp directory in the normal system temp
directory, and cleaning it up on exit.
It is still possible for this temp directory to leak if Python exits
abnormally, but this is probably good enough for now.

Apparently nobody evaluated multiprocessing on Windows since Daniel
enabled multiprocessing on Unix in r193279. It works so far as I can
tell.
Today this is worth about an 8x speedup (631.29s to 73.25s) on my 24
core Windows machine. Hopefully this will improve Windows buildbot cycle
time, where currently it takes more time to run check-all than it does
to self-host with assertions enabled:

This mapping is between pointers, which DenseMap is particularly good
at. Most targets aren't really affected, but if there's a lot of
subregister composition this can shave off a good chunk of time from
