Refactor code to push DILocation prcessing into DwarfDebug.cpp from AsmPrinter.cpp.

This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions.

Fix the third (and last known) case of code update problems due
...
to LLVM IR changes with addr label weirdness. In the testcase, we
generate references to the two bb's when codegen'ing the first
function:
_test1: ## @test1
leaq Ltmp0(%rip), %rax
..
leaq Ltmp1(%rip), %rax
Then continue to codegen the second function where the blocks
get merged. We're now smart enough to emit both labels, producing
this code:
_test_fun: ## @test_fun
## BB#0: ## %entry
Ltmp1: ## Block address taken
Ltmp0:
## BB#1: ## %ret
movl $-1, %eax
ret
Rejoice.

and passing off ownership to AsmPrinter. Now MachineModuleInfo

keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.
