acconfig.h (HAVE_GAS_FILDS_FISTS): Add.

	* acconfig.h (HAVE_GAS_FILDS_FISTS): Add.
	* configure.in: Check assembler instructions.
	* configure: Rebuild.
	* config.in: Likewise.
	* i386.md (floathisf2, floathidf2, floathixf2): New patterns.
	* i386.c (print_operand): Use the proper suffix for a 387 HImode
	operand.  Abort if a 387 operand has an unsupported size.
