f75e5b4d8c Change Feature64Bit to not imply FeatureSSE2. All x86-64 hardware has 
SSE2, however it's possible to disable SSE2, and the subtarget support
code thinks that if 64-bit implies SSE2 and SSE2 is disabled then
64-bit should also be disabled. Instead, just mark all the 64-bit
subtargets as explicitly supporting SSE2.

Also, move the code that makes -march=x86-64 enable 64-bit support by
default to only apply when there is no explicit subtarget. If you
need to specify a subtarget and you want 64-bit code, you'll need to
select a subtarget that supports 64-bit code.

5b93f6fa82 MergeValueInto is too smart: it might choose to do the merge the opposite direction. 
Live interval reconstruction needs to account for this, and scour its maps to
prevent dangling references.

b0d5cdd52e Fix PR3453 and probably a bunch of other potential

getIntegerVTSignBit methods, which returned their
