345ef343cc DwarfDebug: Allocate DIEValues with a BumpPtrAllocator. Most of them are
POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).

~6% less mallocs and ~1% compile time improvement on clang -O0 -g oggenc.c

870cfcf9a6 add new apis for getting/setting !dbg metadata on
instructions.  In addition to being a convenience,
they are faster than the old apis, particularly when
not going from an MDKindID like people should be
doing.

9b97a73ded Rip out the 'is temporary' nonsense from the MCContext interface to
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

5b33f3148c Fix EmitSectionOffset incorrect argument. DwarfDebug is emitting debug info so isEH is always false. This was hiding until now from compilers because of default arguments. This was hiding from dwarf debug info users because for most of the platform isAbsoluteEHSectionOffsets() is same as isAbsoluteDebugSectionOffsets(). But Chris found it while updating dwarf printer to use MC*.

999aee24c7 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.

9cc0da9c29 Implement support for the case when a reference to a addr-of-bb
label is generated, but then the block is deleted.  Since the
value is undefined, we just emit the label right after the entry 
label of the function.  It might matter that the label is in the
same section as the function was afterall.

1611273351 change EH related stuff (other than EH_LABEL) to use MCSymbol
instead of label ID's.  This cleans up and regularizes a bunch 
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.

11d53c129f rearrange MCContext ownership. Before LLVMTargetMachine created it
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.
