Summary:
These can appear when comments contain command lines with quoted line
breaks. As the text (including escaped newlines and '//' from consecutive lines)
is a single line comment, we used to break it even when it didn't exceed column
limit. This is a temporary solution, in the future we may want to support this
case completely - at least adjust leading whitespace when changing indentation
of the first line.

Before, clang-format would simply eat these as they were recognized as
whitespace. With this patch, they are mostly left alone.

These floats all represented block frequencies anyway, so just use the
BlockFrequency class directly.

Some floating point computations remain in tryLocalSplit(). They are
estimating spill weights which are still floats.

llvm-svn: 186435

Original commit message:

Remove floating point computations from SpillPlacement.cpp.

Patch by Benjamin Kramer!

Use the BlockFrequency class instead of floats in the Hopfield network
computations. This rescales the node Bias field from a [-2;2] float
range to two block frequencies BiasN and BiasP pulling in opposite
directions. This construct has a more predictable behavior when block
frequencies saturate.

The per-node scaling factors are no longer necessary, assuming the block
frequencies around a bundle are consistent.

This patch can cause the register allocator to make different spilling
decisions. The differences should be small.

The fundamental concept is:
Format as if the braced init list was a function call (with parentheses
replaced by braces). If there is no name/type before the opening brace
(e.g. if the braced list is nested), assume a zero-length identifier
just before the opening brace.

This behavior is gated on a new style flag, which for now replaces the
SpacesInBracedLists style flag. Activate this style flag for Google
style to reflect recent style guide changes.

Use PMIN/PMAX for UGE/ULE vector comparions to reduce the number of required
instructions. This trick also works for UGT/ULT, but there is no advantage in
doing so. It wouldn't reduce the number of instructions and it would actually
reduce performance.

For safety, the inliner cannot decrease the allignment on an alloca when
merging it with another.

I've included two variants of the test case for this: one with DataLayout
available, and one without. When DataLayout is not available, if only one of
the allocas uses the default alignment (getAlignment() == 0), then they cannot
be safely merged.

Summary:
Add support for CXXCtorInitializer and TemplateArgument types to ASTNodeKind.
This change is to support more matchers from clang/ASTMatchers/ASTMatchers.h in the dynamic layer (clang/ASTMatchers/Dynamic).
