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.

source locations in places where it is necessary for diagnostics.  By itself,
this causes assertions, so while I'm here, also fix property synthesis
for properties of C++ class type so we use so we properly set up a scope
and mark variable declarations.

When merging stack slots, if StackColoring::remapInstructions gets a
value back from GetUnderlyingObject that it does not know about or is
not itself a stack slot, clear the memory operand in case it aliases
the merged slot. This prevents the introduction of incorrect aliasing
information.

This patch migrates the strcpy optimizations from the simplify-libcalls pass
into the instcombine library call simplifier.  Note also that StrCpyChkOpt
has been updated with a few simplifications that were being done in the
simplify-libcalls version of StrCpyOpt, but not in the migrated implementation
of StrCpyOpt.  There is no reason to overload StrCpyOpt with fortified and
regular simplifications in the new model since there is already a dedicated
simplifier for __strcpy_chk.

Within the body of the loop the underlying map may be modified via

  Sema::AddOverloadCandidate
    -> Sema::CompareReferenceRelationship
    -> Sema::RequireCompleteType

to avoid the use of invalid iterators the sequence is copied first.

A reliable, though large, test case is available - it will be reduced and
committed shortly.

<rdar://problem/12068650>

More fixes to how we handle paths that are used to create a target.

This modification centralizes the location where and how what the user specifies gets resolved. Prior to this fix, the TargetList::CreateTarget variants took a FileSpec object which meant everyone had the opportunity to resolve the path their own way. Now both CreateTarget variants take a "const char *use_exe_path" which allows the TargetList::CreateTarget to centralize where the resolving happens and "do the right thing".

test case on PowerPC caused by rounding errors when converting from a 64-bit
integer to a single-precision floating point. The reason for this are
double-rounding effects, since on PowerPC we have to convert to an
intermediate double-precision value first, which gets rounded to the
final single-precision result.

The patch fixes the problem by preparing the 64-bit integer so that the
first conversion step to double-precision will always be exact, and the
final rounding step will result in the correctly-rounded single-precision
result.  The generated code sequence is equivalent to what GCC would generate.

When -enable-unsafe-fp-math is in effect, that extra effort is omitted
and we accept possible rounding errors (just like GCC does as well).

operate purely on values. Sink the alloca loading and storing logic into
the rewrite routines that are specific to alloca-integer-rewrite
driving. This is just a refactoring here, but the subsequent step will
be to reuse the insertion and extraction logic when rewriting integer
loads and stores that have been split and decomposed into narrower loads
and stores.

No functionality changed other than different names for instructions.
