PR target/27968
* configure.ac (HAVE_AS_IX86_FFREEP): On x86 targets check whether
the configured assembler supports the x87's ffreep mnemonic.
* configure: Regenerate.
* config.in: Regenerate.
* config/i386/i386.c (output_387_ffreep): New function.
(output_fp_compare): Use output_387_ffreep to emit ffreep insns.
(output_387_reg_move): Likewise.
