Chris Lattner 628fbecf4f Now that we know if we had a total fail on the instruction mnemonic, 
give a more detailed error.  Before:

t.s:11:4: error: unrecognized instruction
   addl $1, $1
   ^
t.s:12:4: error: unrecognized instruction
   f2efqefa $1
   ^

After:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^
t.s:12:4: error: invalid instruction mnemonic 'f2efqefa'
   f2efqefa $1
   ^

This fixes rdar://8017912 - llvm-mc says "unrecognized instruction" when it means "invalid operands"

Chris Lattner 8130197937 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

Chris Lattner 6b6f3dd994 emit the match table at global scope instead of within the 
MatchInstructionImpl. This makes it easier to read/understand
MatchInstructionImpl.

Chris Lattner 82d88ced92 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.

Chris Lattner fdb7decfaf The "ambiguous instructions" check only produces anything with -debug, 
so only do the N^2 loop with debug mode.

Chris Lattner b4be28f33d 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).

Chris Lattner b01c24a945 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.

Chris Lattner da24b9a49a pull a simple method out of LICM into a new
