Summary:
Some changes are made to cmake, especially the addition of a new
LLVM_ENABLE_PROJECTS option that makes the build system aware of
the monorepo directory structure.
Also a new script is added in llvm/utils/git-svn/. When present in
the $PATH, it enables a `git llvm` command. It is providing at this
point only the ability to push from the git monorepo: `git llvm push`.
It is intended to evolves with more features, for instance I plan on
features like `git llvm show r284955` to help working with sequential
revision numbers.
The push feature is taken from Justin Lebar's script available here:

A large number of tests in the LLVM tree use the default (CHECK) prefix
to indicate checked expressions via FileCheck. Highlight it as a
special comment. Although this wont get all the instances of the
checked patters, it is strictly better than the current state.

2 new intrinsics covering AVX-512 compress/expand functionality.

As it stands, the OperandMatchResultTy is only included in the generated
header if there is custom operand parsing. However, almost all backends
make use of MatchOperand_Success and friends from OperandMatchResultTy for
e.g. parseRegister. This is a pain when starting an AsmParser for a new
backend that doesn't yet have custom operand parsing. Move the enum to
MCTargetAsmParser.h.

The CodeGenSchedModels::checkCompleteness routine in TableGen/
CodeGenSchedule.cpp is supposed to verify for each processor
model that is marked as "complete" that it actually defines a
scheduling class for each instruction.
However, this did not work correctly due to an incorrect
check whether a scheduling class has an itinerary.

In --unified-report mode, a single coverage report is prepared for all
specified binaries and written to *report_dir*. This mode is compatible
with all existing script options, including the --restrict mode which is
used to limit coverage reporting to certain files or directories.
This should not break any existing users of the script.

In --only-merge mode, the script terminates after the profile merging
step. This makes the script less stateful: it's more natural to split
the merge out into a separate step instead of relying on the first
invocation of the script to do it.
This should not break any existing users of the script.

Summary:
SetVector already used DenseSet, but SmallSetVector used std::set. This
leads to surprising performance differences. Moreover, it means that
the set of key types accepted by SetVector and SmallSetVector are
quite different!
In order to make this change, we had to convert some callsites that used
SmallSetVector<std::string, N> to use SmallSetVector<CachedHashString, N>
instead.

-debug-only=subtarget-emitter prints a lot of machine model diagnostics.
This prunes the output so that the "No machine model for XXX on processor YYY"
only appears when there is definitely no machine model for that opcode.
Previously it was printing that error even if the opcode was covered by
a more general scheduling class.

Summary:
The Python file `utils/lit/lit/ShUtil.py` contains:
1. Logic used by lit itself
2. A set of unit tests for that logic, which can be run by invoking
`python utils/lit/lit/ShUtil.py`
Move these unit tests to a `tests/unit` subdirectory of lit, and run
the tests as part of lit's test suite. This ensures that, should the
lit test suite be included in LLVM's own regression test suite, these
unit tests will also be run.
(Instructions on how to run lit's test suite can be found in
`utils/lit/README.txt`.)

Summary:
Using Python linter flake8 on the utils/lit reveals several linter
warnings designated "F401: Unused import". Fix or silence these
warnings.
Some of these unused imports are legitimate, while some are part of lit's API.
For example, users of lit expect to be able to access `lit.formats.ShTest` in
their `lit.cfg`, despite the module hierarchy for that symbol actually being
`lit.formats.shtest.ShTest`. To silence linter errors for these lines,
include a "noqa" directive.

`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`

library.

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.
