These were not recommended by my auto-simplifier since they don't fire often enough.
However they do fire from time to time, for example they remove one subtraction from
the final bitcode for 483.xalancbmk.

simplification in fully optimized code.  It occurs sporadically in the testsuite, and
many times in 403.gcc: the final bitcode has 131 fewer subtractions after this change.
The reason that the multiplies are not eliminated is the same reason that instcombine
did not catch this: they are used by other instructions (instcombine catches this with
a more general transform which in general is only profitable if the operands have only
one use).

McARM: Always keep an offset expression, if used (instead of assuming == 0 if used but not present), and simplify logic.

Also, clean up various non-sensicalisms in isMemModeRegThumb() and isMemModeImmThumb().

Windows/PathV2.inc: MoveFileEx() can behave like Posix's mv(1) to specify MOVEFILE_COPY_ALLOWED | MOVEFILE_REPLACE_EXISTING.

lib/Support/Windows/Signals.inc: "Showstopper" dialogs may be suppressed with SetErrorMode() on Windows 7.

without whatever this was trying to do.  When/if someone has the time to do some empirical
evaluations, it might be worth it to figure out what this code was trying to do and see if
it's worth resurrecting/fixing.
