2170150035 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.

4c8ca99bb1 Improve -fno-opt style option processing to not require an extra 
option to make the -fno- form on the option.  We also document the new
form in the CommandLine documentation.

9d2293f7ad 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.

cac6cf74f9 Fix PR3453 and probably a bunch of other potential 
crashes or wrong code with codegen of large integers:
eliminate the legacy getIntegerVTBitMask and
getIntegerVTSignBit methods, which returned their
value as a uint64_t, so couldn't handle huge types.

e25b96473e Reinstate this optimization to fold icmp of xor when possible. Don't try to 
turn icmp eq a+x, b+x into icmp eq a, b if a+x or b+x has other uses. This
may have been increasing register pressure leading to the bzip2 slowdown.
