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.

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.

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.

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.

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.

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.

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.

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 :-)
