Add support in TableGen for unknown operands that infer their type from the pattern their used in. This will be used to allow insert/extract subreg patterns in .td files!

Start inferring side effect information more aggressively, and fix many bugs in the
...
x86 backend where instructions were not marked maystore/mayload, and perf issues where
instructions were not marked neverHasSideEffects. It would be really nice if we could
write patterns for copy instructions.
I have audited all the x86 instructions down to MOVDQAmr. The flags on others and on
other targets are probably not right in all cases, but no clients currently use this
info that are enabled by default.
