Summary:
As we are going to grow the extension in the near future, it is time to
formalize the TS code format/style of our extension (although we'd lose the
history).

We use default options of clang-format:
- 80 max line length
- 2 space indent

This patch adds support to the WholeProgramDevirt pass to perform
index-based WPD, which is invoked from ThinLTO during the thin link.

The ThinLTO backend (WPD import phase) behaves the same regardless of
whether the WPD decisions were made with the index-based or (the
existing) IR-based analysis.

Depends on D54815.

The parameter to the -D (--dllname) option is the name of the dll
that llvm-dlltool produces an import library for. Even though this
is named "OutputFile" in the COFFModuleDefinition class, it's not
an output file name in the context of llvm-dlltool, but the name
of the DLL to create an import library for.

[MCA] Add support for printing immedate values as hex. Also enable lexing of masm binary and hex literals.

This patch adds a new llvm-mca flag named -print-imm-hex.

By default, the instruction printer prints immediate operands as decimals. Flag
-print-imm-hex enables the instruction printer to print those operands in hex.

This patch also adds support for MASM binary and hex literal numbers (example
0FFh, 101b).
Added tests to verify the behavior of the new flag. Tests also verify that masm
numeric literal operands are now recognized.

This optimisation isn't generally profitable for ARM, because we can
save/restore many registers in the prologue and epilogue using the PUSH
and POP instructions, but mostly use individual LDR/STR instructions for
other spills.

- Avoid a crash when IPRA calls ARMFrameLowering::determineCalleeSaves
  with a null RegScavenger. Simply not updating the register scavenger
  is fine because IPRA only cares about the SavedRegs vector, the acutal
  code of the function has already been generated at this point.
- Add a new hook to TargetRegisterInfo to get the set of registers which
  can be clobbered inside a call, even if the compiler can see both
  sides, by linker-generated code.

This patch adds an ability to disable profile based peeling 
causing the peeling of all iterations and as a result prohibits
further unroll/peeling attempts on that loop.

The motivation to get an ability to separate peeling usage in
pipeline where in the first part we peel only separate iterations if needed
and later in pipeline we apply the full peeling which will prohibit further peeling.

Summary:
TweakTests.cpp has some pretty good helpers added for the first few
tweaks, but they have some limitations:
 - many assertion failures point at the wrong line
 - need lots of input/output tests, setup code is duplicated across both
 - local helpers make it hard to split the file as it grows

The new helpers in TweakTests.h are based on old ones (same operations)
but try to address these issues and generally make tests more terse
while improving error messages.

This patch converts everything except ExtractVariable (which is complex
and has changes in flight, so will be converted later).
It's LOC-neutral, despite not being able to get rid of the old helpers
until ExtractVariable is done.

Summary:
This is the next step in avoiding funneling all SymbolFile calls through
the SymbolVendor. Right now, it is just a convenience function, but it
allows us to update all calls to SymbolVendor functions to access the
SymbolFile directly. Once all call sites have been updated, we can
remove the GetSymbolVendor member function.

This patch just updates the calls to GetSymbolVendor, which were calling
it just so they could fetch the underlying symbol file. Other calls will
be done in follow-ups.

The unit tests in BasicAliasAnalysisTest use the alias analysis API
directly and do not call setAAResults to initalize AAR. This gives a
valgrind error "Conditional Jump depends on unitialized variable".

On most buildbots the variable is nullptr, but in some cases it can be
non nullptr leading to seemingly random failures.

These tests were disabled in r366986. With the initialization they can be
enabled again.

1. raw_ostream supports ANSI colors so that you can write messages to
the termina with colors. Previously, in order to change and reset
color, you had to call `changeColor` and `resetColor` functions,
respectively.

So, if you print out "error: " in red, for example, you had to do
something like this:

  OS.changeColor(raw_ostream::RED);
  OS << "error: ";
  OS.resetColor();

With this patch, you can write the same code as follows:

  OS << raw_ostream::RED << "error: " << raw_ostream::RESET;

2. Add a boolean flag to raw_ostream so that you can disable colored
output. If you disable colors, changeColor, operator<<(Color),
resetColor and other color-related functions have no effect.

Most LLVM tools automatically prints out messages using colors, and
you can disable it by passing a flag such as `--disable-colors`.
This new flag makes it easy to write code that works that way.

Current peeling cost model can decide to peel off not all iterations
but only some of them to eliminate conditions on phi. At the same time 
if any peeling happens the door for further unroll/peel optimizations on that
loop closes because the part of the code thinks that if peeling happened
it is profile based peeling and all iterations are peeled off.

To resolve this inconsistency the patch provides the flag which states whether
the full peeling basing on profile is enabled or not and peeling cost model
is able to modify this field like it does not PeelCount.

In a separate patch I will introduce an option to allow/disallow peeling basing
on profile.

To avoid infinite loop peeling the patch tracks the total number of peeled iteration
through llvm.loop.peeled.count loop metadata.
