f3caa525cc X86 address mode matching code MatchAddressRecursively does some aggressive hack which require doing a RAUW. It may end up deleting some SDNode up stream. It should avoid referencing deleted nodes.

4e815f8a8c MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr. 
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

1bbf72b069 Recognize code for doing vector gather/scatter index calculations with 
32-bit indices. Instead of shuffling each element out of the index vector,
when all indices are needed, just store the input vector to the stack and
load the elements out.

757e75b033 Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing 
to is local to the translation unit, we need to place fill the value of that
symbol into the non-lazy pointer.

This should conclude all Darwin changes for placing the LSDA into the TEXT
section. There is some cleanup to do. I.e., there's no longer a special need for
target-specific code here. But that can come later.

166604e6ce shrink 4-byte branches to 1-byte branches when lowering from

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.
