0a7befa8bd eliminate the ExtWeakSymbols set from AsmPrinter. This eliminates
a bunch of code from all the targets, and eliminates nondeterministic
ordering of directives being emitted in the output.

b13bafe5c1 On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body.

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.

6679ee4e80 RecordVariable is called each time a DECLARE node is encountered. For an inlined
function, this could be many, many times. We don't want to re-add variables to

we haven't added them already.

logical/sane approach to organizing all of the stuff that goes into writing out

be doing.

f59d10f1bc There's yet more ugliness (surprise!) in DebugInfo. This needs major reworking.
Basically, there was a situation where it was getting an empty vector and doing
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.

e688fafd38 Compute the offsets of the compile units. We need this so that when we emit a

abstract instance inside of the compile unit.
