now that the opcode is trivially exposed, start matching instructions

by doing a binary search over the mnemonic instead of doing a linear
search through all possible instructions. This implements rdar://7785064

special case the mnemonic operand of the instruction in the
...
generated matcher, emiting it as a column in the MatchEntry
table instead of forcing it to go through classification and
everything else. Making it be classified caused tblgen to
produce a ton of one-off classes for each mneumonic. This
should reduce the size of the generated matcher significantly
while paving the way for future improvements.

have tblgen detect when an instruction would have matched, but
...
failed because a subtarget feature was not enabled. Use this to
remove a bunch of hacks from the X86AsmParser for rejecting things
like popfl in 64-bit mode. Previously these hacks weren't needed,
but were important to get a message better than "invalid instruction"
when used in the wrong mode.
This also fixes bugs where pushal would not be rejected correctly in
32-bit mode (just pusha).

Teach loop rotate to hoist trivially invariant instructions
...
in the duplicated block instead of duplicating them.
Duplicating them into the end of the loop and the preheader
means that we got a phi node in the header of the loop,
which prevented LICM from hoisting them. GVN would
usually come around later and merge the duplicated
instructions so we'd get reasonable output... except that
anything dependent on the shoulda-been-hoisted value can't
be hoisted. In PR5319 (which this fixes), a memory value
didn't get promoted.
