c50b8b27f5 fix PR6605, X86ISD::CMP always returns i32 (EFLAGS), not
the operand type.

2bdb0765f8 fix AsmPrinter::GetBlockAddressSymbol to always return a unique
label instead of trying to form one based on the BB name (which
causes collisions if the name is empty).  This fixes PR6608

239d05bad6 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

5fef80c5aa 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".

they should have been emitted.

149cf816bb 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.

e7538fa303 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.
