Update processDebugLoc() to handle requests to process debug info, before and after emitting instructions.

Update processDebugLoc() so that it can be used to process debug info before and after printing an instruction.

llvm-svn: 83362

This will be used by processDebugLoc().

Existence of a compile unit for input source file is a good indicator to check debug info's presence in a module.

llvm-svn: 83348

This can happen if debug info is processed lazily.

void foo() { static int bar = 42; }
Here, foo's DIE is parent of bar's DIE.

spill slot. When frame references are via the frame pointer, they will be
negative, but Thumb1 load/store instructions only allow positive immediate
offsets. Instead, Thumb1 will spill to R12.

Fixes second part of PR5130, miscompilation in FreeBSD kernel, where malloc takes 3 params,
and *does* initialize memory.

pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

Do away with the strange use of BitVectors in SSI, and just use normal sets.  This makes the code much more C++/LLVM-ish.
