[Bug gas/707] New: intel syntax vs 'fnstcw ' and 'fldcw'

[dannysmith at users dot sourceforge dot net]

The following C code
void foo()
{
  unsigned short _cw;
  __asm__ volatile ("fnstcw %0;": "=m" (_cw));
  __asm__ volatile ("fldcw %0;" : : "m" (_cw));
}

produces with gcc -mintel-syntax

        .file   "asm.c"
        .intel_syntax
        .text
.globl _foo
        .def    _foo;   .scl    2;      .type   32;     .endef
_foo:
        push    ebp
        mov     ebp, esp
        sub     esp, 16
/APP
        fnstcw WORD PTR [ebp-2];
        fldcw WORD PTR [ebp-2];
/NO_APP
        leave
        ret

as (2.15.94 20050118) emits an error assembling this

asm.s: Assembler messages:
asm.s:11: Error: suffix or operands invalid for `fnstcw'
asm.s:12: Error: suffix or operands invalid for `fldcw'

Earlier version of as (GNU assembler 2.15.91 20040904) handled the code without 
an error report.

AT&T syntax works fine.
