7d4cb40969 all 64-bit cpus have cmov, this should fix CodeGen/X86/cmov.ll 
(at least) on non-x86 builders.

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.
