166604e6ce shrink 4-byte branches to 1-byte branches when lowering from 
MachineInstr -> MCInst.  This is what the assembler backend wants,
it relaxes from smaller to larger things.  This fixes rdar://7750815

63d7836267 get MMI out of the label uniquing business, just go to MCContext 
to get unique assembler temporary labels.

2e9919a5e5 Now that DBG_LABEL is updated, we can finally make MachineMove

7561d48095 change the LabelSDNode to be EHLabelSDNode and make it hold 
an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

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.
