Rationale:
1) This was the name in the comment block. ;]
2) It matches Clang's __has_feature naming convention.
3) It matches other compiler-feature-test conventions.

Sorry for the noise. =]

I've also switch the comment block to use a \brief tag and not duplicate
the name.

appropriate unit tests. This change in itself is not expected to
affect any functionality at this point, but it will serve as a
stepping stone to improve FileCheck's variable matching capabilities.

Luckily, our regex implementation already supports backreferences,
although a bit of hacking is required to enable it. It supports both
Basic Regular Expressions (BREs) and Extended Regular Expressions
(EREs), without supporting backrefs for EREs, following POSIX strictly
in this respect. And EREs is what we actually use (rightly). This is
contrary to many implementations (including the default on Linux) of
POSIX regexes, that do allow backrefs in EREs.

Adding backref support to our EREs is a very simple change in the
regcomp parsing code. I fail to think of significant cases where it
would clash with existing things, and can bring more versatility to
the regexes we write. There's always the danger of a backref in a
specially crafted regex causing exponential matching times, but since
we mainly use them for testing purposes I don't think it's a big
problem. [it can also be placed behind a flag specific to FileCheck,
if needed].

The SectionMemoryManager now supports (and requires) applying section-specific page permissions.  Clients using this memory manager must call either MCJIT::finalizeObject() or SectionMemoryManager::applyPermissions() before executing JITed code.

See r168718 for changes from the previous implementation.

This commit is primarily here for the revision history.  I'm about to move the SectionMemoryManager into the RuntimeDyld library, but I wanted to check the changes in here so people could see the differences in the updated implementation.

The rationale is to get YAML filenames in diagnostics from
yaml::Stream::printError -- currently the filename is hard-coded as
"YAML" because there's no buffer information available.

Add a new function to ConstantExpr - getAsInstruction. This returns its Instruction* corollary, which may be useful if a user
wishes to transform a ConstantExpr so that one of its operands is no longer constant.

do not play preprocessor tricks with 'private', use public interfaces instead; this appeases the VC++ buildbots

ICC refuses to compile a class in an anonymous namespace if some functions
aren't defined. Fixes PR13477.

This is safe for x87 long doubles and ppc double doubles too.

MCJIT unit test: add calls to ensure that instruction caches are properly invalidated before code execution.

These tests were all failing since the old JIT doesn't work
for PowerPC (any more), and there are no plans to attempt to
fix it again (instead, work focuses on MCJIT).

treating it as if it were an IEEE floating-point type with 106-bit
mantissa.

This makes compile-time arithmetic on "long double" for PowerPC
in clang (in particular parsing of floating point constants)
work, and fixes all "long double" related failures in the test
suite.

Fixed bug in SmallDenseMap where it wouldn't leave enough space for an empty bucket if the number of values was exactly equal to the small capacity.  This led to an infinite loop when finding a non-existent element

When building with LTO, the internalize pass is hiding some global symbols
that are necessary for the JIT unittests. It seems like that may be a bug in
LTO to do that by default, but until that gets fixed, this change makes sure
that we export the necessary symbols for the tests to pass.

Fix a bug in the set(I,E)/reset(I,E) methods that I recently added.  The boundary condition for checking if I and E were in the same word were incorrect, and, beyond that, the mask computation was not using a wide enough constant.

Add range-based set()/reset() to BitVector.  These allow fast setting/resetting of ranges of bits, particularly useful when dealing with very large BitVector's.
