Revert r108369, sorting llvm.dbg.declare information by source position,
since it doesn't work for front-ends which don't emit column information
(which includes llvm-gcc in its present configuration), and doesn't
work for clang for K&R style variables where the variables are declared
in a different order from the parameter list.

Instead, make a separate pass through the instructions to collect the
llvm.dbg.declare instructions in order. This ensures that the debug
information for variables is emitted in this order.

The JIT calls TidyLandingPads to tidy up the landing pads. However, because the
JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
section for the MCSymbol is never set. And thus the MCSymbol for the EH label
isn't marked as "defined". Because of that, TidyLandingPads removes the needed
landing pads from the JIT output. This breaks EH for every JIT program.

This is a work-around for this limitation. We pass in the label locations
map. If the label has a non-zero value, then it was "emitted" by the JIT and
TidyLandingPads shouldn't remove that label.

A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
upon the section being set to determine if it's defined or not.

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.

of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places. This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction. There should not be any
functionality change from doing this, but I'm not an EH expert.
