df967d6137 fix rdar://8470918 - llvm-mc can't assemble smovl

cb296ec0b6 Fix rdar://8468087 - llvm-mc commutes fmul (and friend) operands. 
My previous fix for rdar://8456371 should only apply to fmulp/faddp,
not to fmul/fadd.  Instruction set orthogonality is overrated or 
something.

1eb1b68e3a Fix an inconsistency in the x86 backend that led it to reject "calll foo" on 
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.

cbf8a98c7c fix the asmparser so that the target is responsible for skipping to 
the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors.  Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:

  foo %eax
  bar %al

This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

ce4a3355d9 in the case where an instruction only has one implementation 
of a mneumonic, report operand errors with better location
info.  For example, we now report:

t.s:6:14: error: invalid operand for instruction
        cwtl $1
             ^

but we fail for common cases like:

t.s:11:4: error: invalid operand for instruction
   addl $1, $1
   ^

because we don't know if this is supposed to be the reg/imm or imm/reg
form.

a008e8ac73 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

   ^
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

ec6789f4f9 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).
