5e88bf4c00 Make this test more thorough. Not only should there be no %esi, 
there should be no spilling of anything.

34889f5bed GlobalOpt only process non constant local GVs while optimizing global vars. 
If non constant local GV named A is used by a constant local GV named B (e.g. llvm.dbg.variable) and B is not used by anyone else then eliminate A as well as B.

In other words, debug info should not interfere in removal of unused GV.

c4f40d1f53 Daniel wanted the stack printed upside down. Perhaps he 
feels a kinship to machine stacks that grow down.  Now we get
stuff like this:

ec80b49533 When allocating stubs, keep track of which Functions are referencing the stub. 
This invalidates the stubs in the resolver map when they are no longer referenced,
and should the JIT memory manager ever pick up a deallocateStub interface, the
JIT could reclaim the memory for unused stubs as well.

faf39c40d4 Add a new 'AddSignalHandler' function to Signals.h that allows 
arbitrary functions to be run when a crash happens.  Delete 
RemoveDirectoryOnSignal as it is dead and has never had clients.

Change PrintStackTraceOnErrorSignal to be implemented in terms of
AddSignalHandler.

I updated the Win32 versions of these APIs, but can't test them.
If there are any problems, I'd be happy to fix them as well.

9a8e64c76f Give sentinel traits the right to determine the policy where the sentinel is kept. 
This should result in less indirect memory accesses, less dead writes and tighter code.

04453ca36c When using MachineInstr operand indices on SDNodes, the number 
of MachineInstr def operands must be subtracted out. This bug
was uncovered by the recent x86 EFLAGS optimization. Before
that, the only instructions that ever needed unfolding were
things like CMP32rm, where NumDefs is zero.

511a668cd1 Fix a thinko in the JIT where the address of a GV was only recorded in the map 
on failure to resolve it.
Do not abort on failure to resolve an external symbol when using dlsym stubs,
  since the symbol may not be in the JIT's address space.  Just use 0.
Allow dlsym stubs to differentiate between GlobalVars and Functions.

b75225556d Fix BuildVectorSDNode::isConstantSplat to handle one-element vectors. 
It is an error to call APInt::zext with a size that is equal to the value's
current size, so use zextOrTrunc instead.

f8d2f7429d "Ghostify" embedded sentinels. This is a real win in all cases 
because less bytes are allocated and subobject construction is gone.
For reference how it works, see BasicBlock.h.
Btw. it is very assuring to see that somebody has invented
this ilist-embedded sentinel technique before me :-)

db402a7a49 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.
