This reverts commit r205974, it turns out that this wasn't such a great idea
after all. Using DIVariable as return value is self-documenting and marginally
more type safe.

The "unexpected value" message only matters to me, but is bound to make the experience more confusing for people when some uninitialized memory looks like an NSNumber and then can't be formatted properly, and that error comes out in the UI

Just drop the error message entirely - nobody but me cares

Emitting the PGO initialization in EmitGlobalFunctionDefinition is
inefficient, since this only has an effect once per module.  We move
this to Release() with the rest of the once-per-module logic.

llvm-svn: 205977

Some minor improvements to the thread safety intermediate language -- mostly const correctness and reformatting. Fixes the types involved with castOpcode().

With the VFS, it is easy to hit modified umbrellas by overriding the
umbrella header, and what we want is to rebuild, not to fail.

Summary:
Similarly, the HasMips64 on the 64-bit move InstAlias is a test for 64-bit
GPR's.

No functional change.

This commit reapplies 205018. After 205855 we should correctly vectorize
intrinsics.

llvm-svn: 205965

Summary:
It is now the smallest superset for these ISA's.

FeatureMips4 now contains FeatureFPIdx since [ls][dw]xc1 were added in MIPS-IV.
Made the FPIdx feature bit lowercase so that it can be used in the -mattr option.

Depends on D3274

for example from the included testcase:

-> 15       a = 4;

(int) $1 = 2
(lldb) p d

FIXME: Could we use SmallString here?
llvm-svn: 205950

GCC 4.8 complains with:
  warning: enumeral and non-enumeral type in conditional expression

Although this is silly and harmless in this case, add an explicit cast to
silence the warning.

If we crash, we raise a crash handler dialog, and that's really
annoying.  Even though we can't emit correct IR until we have musttail,
don't crash.

The immediate cost calculation code was hitting an assertion in the included
test case, because APInt was still internally 128-bits. Truncating it to 64-bits
fixed the issue.

Revert "For the ARM integrated assembler add checking of the alignments on vld/vst instructions.  And report errors for alignments that are not supported."

It doesn't build with MSVC 2012, because MSVC doesn't allow union
members that have non-trivial default constructors.  This change added
'SMLoc AlignmentLoc' to MemoryOp, which made MemoryOp's default ctor
non-trivial.

This reverts commit r205930.

As it turns out the source of the sunkaddr can be a constant, in which case
there is not an instruction to delete, causing the cleanup code introduced in
r204833 to crash. This patch adds a dynamic check to ensure the deleted value is
in fact an instruction and not a constant.
