9f3f061d74 Revise my previous change to ExpandBIT_CONVERT. I hadn't realized that this
may be called when either the source or destination type is i64, and my
change also hadn't fixed the most obvious problem -- assuming that i64 will
only be bitconverted to f64, ignoring the various vector types.

84bd6b0c31 Re-commit my previous SSAUpdater changes. The previous version naively tried
to determine where to place PHIs by iteratively comparing reaching definitions
at each block.  That was just plain wrong.  This version now computes the
dominator tree within the subset of the CFG where PHIs may need to be placed,
and then places the PHIs in the iterated dominance frontier of each definition.
The rest of the patch is mostly the same, with a few more performance
improvements added in.

Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

bde0bb5f88 building on the new CallGraphSCC abstraction, teach CallGraphSCCPassManager
to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.

Thanks to Dale for expertly hunting it down.

c7b65914e0 Fixed a bug in DisassembleN1RegModImmFrm() where a break stmt was missing for a
case.  Also, the 0xFF hex literal involved in the shift for ESize64 should be
suffixed "ul" to preserve the shift result.

Implemented printHex*ImmOperand() by copying from ARMAsmPrinter.cpp and added a
test case for DisassembleN1RegModImmFrm()/printHex64ImmOperand().
