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.

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:

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.

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

failed because a subtarget feature was not enabled. Use this to

when used in the wrong mode.
This also fixes bugs where pushal would not be rejected correctly in
