libgcc: Pass x87 control word in the correct type
The x87 control word should be passed as an `unsigned short`. Previous
code passed `unsigned int`, and when building with `-masm=intel`,
__asm__ __volatile__ ("fnstcw\t%0" : "=m" (_cw));
could expand to `fnstcw DWORD PTR [esp+48]` and cause errors like
{standard input}: Assembler messages:
{standard input}:7137: Error: operand size mismatch for `fnstcw'
libgcc/ChangeLog:
PR target/122275
* config/i386/32/dfp-machine.h (DFP_GET_ROUNDMODE): Change `_frnd_orig` to
`unsigned short` for x87 control word.
(DFP_SET_ROUNDMODE): Manipulate the x87 control word as `unsigned short`,
and manipulate the MXCSR as `unsigned int`.
