524eb5859f Fix handling of the From parameter in StringRef::find. 
Enable bounds checking to catch this kind of bug earlier.

5d4f239d0a Add a call to EmitSjLjDispatchBlock. 
Once the intrinsics are marked as having a custom inserter, it will call this
method to emit the dispatch table into the machine function.

expanding conditional moves, which is not needed since architectures that lack
support for conditional moves have been removed.

1910496fb4 Admonish that MI is not IR and virtual registers have constraints. 
In machine code, you can't just replaceRegWith() the same way you can
replaceAllUsesWith() in IR.  Virtual registers may have different
register classes that need to be merged first.

9c33ff8a8b Add a routine to swap branch instruction operands, and update any 
profile metadata at the same time. Use it to preserve metadata attached
to a branch when re-writing it in InstCombine.

Add metadata to the canonicalize_branch InstCombine test, and check that
it is tranformed correctly.
