Added the notion of a "boundable region", which is a region that can have a direct binding in the StoreManager.

per Chris' suggestion.  Slightly faster.

Fix PR3701. 1. X86 target renamed eflags register to flags. This matches what llvm-gcc generates so codegen knows flags register is being clobbered by inline asm. 2. BURR scheduler should also check if inline asm nodes can clobber "live" physical registers. Previously it was only checking target nodes with implicit defs.

If a global constant is dead then global's debug info should not prevent the optimizer in deleting the global. And while deleting global, delete global's debug info also.

when counting work; it was only off by 1.

While the patch is clearly correct in itself, it's become
apparent other places are assuming debug intrinsics are
marked as touching memory...this needs more testing.

so it changed it into a 31 via the TLO.ShrinkDemandedConstant() call. Then it
would go through the DAG combiner again. This time it had a value of 31, which
was turned into a -1 by TLI.SimplifyDemandedBits(). This would ping pong
forever.

Teach the TLO.ShrinkDemandedConstant() call not to lower a value if the demanded
value is an XOR of all ones.

RegionStore::RemoveDeadBindings needs to check all the symbols of the super region of a scanned region as well.

conclusions are our PCH generation is way faster than gcc, and the
Python based driver kills compile times.

Fix <rdar://problem/5982579> [clang on xcode] (using arch=x86_64): synthesized property 'sdkPath' must either be named the same as a compatible ivar or must explicitly name an ivar.

SVal::getAsLocSymbol(). This simplifies the code and allows the retain/release
checker to (I believe) also correctly reason about location symbols wrapped in
SymbolicRegions.

Along the way I cleaned up SymbolRef a little, disallowing implicit casts to
'unsigned'.

use, check also for the case where it has two uses,
the other being a llvm.dbg.declare.  This is needed so
debug info doesn't affect codegen.

and defining target-specific macros based on them (like __SSE3__ and 
friends).  After extensive discussion with Daniel, this work will need
driver support, which will translate things like -msse3 into a -mattr 
feature.  Until this work is done, the code in clang.cpp is disabled and
the X86TargetInfo ctor still defaults to SSE2.  With these two things
changed, this code will work.  PR3634
