Register pressure tracking is half the complexity of the
scheduler. It's useful to be able to turn it off for compile time and
performance comparisons.

'Force' values in registers using the calling convention. Now, we only depend on
the calling convention and that the allocator performs copy coalescing.

* It was redundant with -flto.
* It was confusing since -uAnythingElse is a different option.
* GCC uses -fuse-linker-plugin, so it was not even a compatibility option.

These instructions, such as vmul.f32, require the second source operand to
be in D0-D15 rather than the full D0-D31. When optimizing, make sure to
account for that by constraining the register class of a replacement virtual
register to be compatible with the virtual register(s) it's replacing.

I've been unsuccessful in creating a non-fragile regression test. This issue
was detected by the LLVM nightly test suite running on an A15 (Bullet).

Unaligned vldm/vstm need more uops and therefore are slower in general on swift.

There is no reason to expect this tool to be limited to C++11, it seems
very likely to be of on-going interest. It seems likely to be useful for
modernizing even as new libraries come out in TSes and other formats
than a complete standard. Fundamentally, we need something a bit more
general. After some discussion on the list, going with
'clang-modernize'.

I've tried to do a reasonably comprehensive job of fixing up the names,
but I may still have missed some. Feel free to poke me if you spot any
fallout here. Things I've tried reasonably hard to find and fix:

- cpp11-migrate -> clang-modernize
- Migrator -> Modernizer
- Clean up the introductory documentation that was C++11 specific.

I'll also point out that this tool continues to delight me. =] Also,
a huge thanks to those who have so carefully, thoroughly documented the
tool. The docs here are simply phenomenal. Every tool should be this
well documented. I hope I have updated the documentation reasonably
well, but I'm not very good at documentation, so review much
appreciated.

Added a "sources.py" which adds a command that can print out the source files contained in one or more modules.

Added "mach_o.py" which is a mach-o parser that can dump mach-o file contents and also extract sections. It uses the "file_extract" module and the "dict_utils" module.

Fix scheduling for vldm/vstm instructions that load/store more than 32 bytes on Cortex-A9. This also makes the existing code more compact.

The NoProblemsDependencies.modularize test is failing on many buildbots.
I have also reverted the change in 189904 to disable that test for MSVC.

This reverts commit r189886.

I found a corner case where this optimization is not valid:

Say we have a "linkonce_odr unnamed_addr" in two translation units:
* In TU 1 this optimization kicks in and makes it hidden.
* In TU 2 it gets const merged with a constant that is *not* unnamed_addr,
  resulting in a non unnamed_addr constant with default visibility.
* The static linker rules for combining visibility them produce a hidden
  symbol, which is incorrect from the point of view of the non unnamed_addr
  constant.

The one place we can do this is when we know that the symbol is not used from
another TU in the same shared object, i.e., during LTO. I will move it there.

Move generic isPrint and columnWidth implementations to a separate header/source to allow using both generic and system-dependent versions on win32.

Summary:
This is needed so we can use generic columnWidthUTF8 in clang-format on
win32 simultaneously with a separate system-dependent implementations of
isPrint/columnWidth in TextDiagnostic.cpp to avoid attempts to print Unicode
characters using narrow-character interfaces (which is not supported on Windows,
and we'll have to figure out how to handle this).
