33852b4f35 Sprinkle some PrettyStackEntry magic into the passmanager. With this, we now 
get nice and happy stack traces when we crash in an optimizer or codegen.  For
example, an abort put in UnswitchLoops now looks like this:

Stack dump:
0.	Program arguments: clang pr3399.c -S -O3 
1.	<eof> parser at end of file
2.	per-module optimization passes
3.	Running pass 'CallGraph Pass Manager' on module 'pr3399.c'.
4.	Running pass 'Loop Pass Manager' on function '@foo'
5.	Running pass 'Unswitch loops' on basic block '%for.inc'
Abort

42049dafd7 Fix ScheduleDAGRRList::CopyAndMoveSuccessors' handling of nodes 
with multiple chain operands. This can occur when the scheduler
has added chain operands to a node that already has a chain
operand, in order to handle physical register dependencies.

This fixes an llvm-gcc bootstrap failure on x86-64 introduced
in r66058.

fbcb5235b0 Fix a parallel make race condition by swapping the order of -I directories. 
The .cmi files are generated in $(ObjDir) and then copied to $(OcamlDir).
The ocamldep output references the .cmi files in $(ObjDir), so make kicks
off a dependent compile as soon as the local copy is generated.  If the
copy to $(OcamlDir) is not complete at that point, the compiler will read
the partially copied file and complain about a "Corrupted compiled
interface".  Searching $(ObjDir) first avoids this.

f9599e6c5f Don't use plain INC32 and DEC32 on x86-64; it needs 
INC64_32r and INC64_16r, because these instructions are encoded
differently on x86-64. This fixes JIT regressions on x86-64 in
kimwitu++ and others.

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.
