Bill Wendling 506b304706 Rewrite CorrectExtraCFGEdges() to make it more understandable. 
* Set the "DestA" and "DestB" according to how they're understood by the
  method. I.e., if one or both of them should point to the "fall through" block,
  then point to the fall through block.

* Improve the loop that removes superfluous edges to be more understandable.

Stuart Hastings f3e5afd6d3 Debug info can now properly represent functions inside classes inside other functions. Partial fix for Radar 7424645.

Bob Wilson ac229124f4 Rewrite part of the SSAUpdater to be more careful about inserting redundant 
PHIs.  The previous algorithm was unable to reliably detect when existing
PHIs in a cycle can be reused.  I'm still working on reducing a testcase.

Dale Johannesen b67a6e6620 Fix a nasty dangling-pointer heisenbug that could 
generate wrong code pretty much anywhere AFAICT.
A case that hits the bug reproducibly is impossible,
but the situation was like this:
Addr = ...
Store -> Addr
Addr2 = GEP , 0, 0
Store -> Addr2
Handling the first store, the code changed replaced Addr
with a sunkaddr and deleted Addr, but not its table
entry.  Code in OptimizedBlock replaced Addr2 with a
bitcast; if that happened to reuse the memory of Addr,
the old table entry was erroneously found when handling
the second store.

POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).

~6% less mallocs and ~1% compile time improvement on clang -O0 -g oggenc.c

Chris Lattner 009de335ac add new apis for getting/setting !dbg metadata on 
instructions.  In addition to being a convenience,
they are faster than the old apis, particularly when
not going from an MDKindID like people should be
doing.

Chris Lattner c263b42d0d Fix a major source of compile-time slowness at -O0 -g by optimizing 
the storage of !dbg metadata kinds in the instruction themselves.
The on-the-side hash table works great for metadata that not-all
instructions get, or for metadata that only exists when optimizing.
But when compile-time is everything, it isn't great.

I'm not super thrilled with the fact that this plops a TrackingVH in
Instruction, because it grows it by 3 words.  I'm investigating 
alternatives, but this should be a step in the right direction in any
case.

Jakob Stoklund Olesen 3493398f13 V_SETALLONES is an integer instruction. 
Since it is just a pxor in disguise, we should probably expand it to a full
polymorphic triple.

Jakob Stoklund Olesen dbff4e8103 Renumber SSE execution domains for better code size. 
SSEDomainFix will collapse to the domain with the lower number when it has a
choice. The SSEPackedSingle domain often has smaller instructions, so prefer
that.

Mon P Wang 7460571381 Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset, 
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

Chris Lattner 9897043928 Rip out the 'is temporary' nonsense from the MCContext interface to
