5bcc8bd0c6 Remove unused AsmPrinter OptLevel argument, and propogate. 
- This more or less amounts to a revert of r65379. I'm curious to know what
   happened that caused this variable to become unused.

daf9e02893 llvm.dbg.region.end() intrinsic is not required to be in _last_ basic block in a function. If that happens then any basic block that follows (lexically) the block with regin.end will not have scope info available. LexicalScopeStack relies on processing basic block in CFG order, but this processing order is not guaranteed. Things get complicated when the optimizer gets a chance to optimizer IR with dbg intrinsics. 
Apply defensive patch to preserve at least one lexical scope till the end of function.

we haven't added them already.

a .back() on that. Which isn't cool.

a5c8a4e4e6 This is a large rewrite of how Dwarf info for inlined functions is handled. 
The DwarfWriter expects DbgScopes and DIEs to behave themselves according to
DwarfWriter's rules. However, inlined functions violate these rules. There are
two different types of DIEs associated with an inlined function: an abstract
instance, which has information about the original source code for the function
being inlined; and concrete instances, which are created for each place the
function was inlined and point back to the abstract instance.

This patch tries to stay true to this schema. It bypasses how regular DbgScopes
and DIEs are created and used when necessary. It provides special handling for
DIEs of abstract and concrete instances.

This doesn't take care of all of the problems with debug info for inlined
functions, but it's a step in the right direction. For one thing, llvm-gcc
generates wrong IR (it's missing some llvm.dbg intrinsics at the point where the
function's inlined) for this example:

#include <stdio.h>
static __inline__ __attribute__((always_inline))  int bar(int x) { return 4; }
void foo() {
  long long b = 1;
  int Y = bar(4);
  printf("%d\n", Y);
}

while clang generates correct IR.
