abf1d4e9db Function temporaries can not overlap with retval or args.See the comment in source code to know the reason. Anything having .auto. in its name is local to a function in nature irrespective of the linkage specified. print static local variables in module level IDATA section.

5de6cc843a make sure that BranchInst::getSuccessor() does not assert in cast<> 
even if the underlying operand is NULL. This may happen in debugging context
within opt with partial loop unrolling (see test/Transforms/LoopUnroll/partial.ll).
After this fix I can resubmit the (backed out) r63459:
* lib/VMCore/AsmWriter.cpp: use precise accessors.

9dc1507838 Turns out AnalyzeBranch can modify the mbb being analyzed. This is a nasty 
suprise to some callers, e.g. register coalescer. For now, add an parameter
that tells AnalyzeBranch whether it's safe to modify the mbb. A better
solution is out there, but I don't have time to deal with it right now.

d5f5c0660b r64073 commit message is lost. Here it is: 
Right now if the coalesced copy def is dead and its src is a kill, and that
there are now other uses within the live range, the coalescer would mark the
def of the source register as dead. But it should also check if there are
other kills which means the value has other uses not in the live range.

a259483aae Get rid of the last non-DebugLoc versions of getNode! 
Many targets build placeholder nodes for special operands, e.g.
GlobalBaseReg on X86 and PPC for the PIC base.  There's no
sensible way to associate debug info with these.  I've left
them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. 
I'm not too happy about this but don't see a good improvement;
I considered adding a getPseudoOperand or something, but it
seems to me that'll just make it harder to read.

there.  UNDEF doesn't logically have DebugLoc; add
