Add support for floating-point fused multiply-add on Sparc.
* configure.ac: Add feature check to make sure the assembler
supports the FMAF, HPC, and VIS 3.0 instructions found on
Niagara-3 and later cpus.
* configure: Rebuild.
* config.in: Likewise.
* config/sparc/sparc.opt: New option '-mfmaf'.
* config/sparc/sparc.md: Add float fused multiply-add patterns.
* config/sparc/sparc.h (AS_NIAGARA3_FLAG): New macro.
(ASM_CPU64_DEFAULT_SPEC, ASM_CPU_SPEC): Use it, as needed.
* config/sparc/sol2.h (ASM_CPU32_DEFAULT_SPEC,
ASM_CPU64_DEFAULT_SPEC, ASM_CPU_SPEC): Likewise.
* config/sparc/sparc.c (sparc_option_override): Turn MASK_FMAF on
by default for Niagara-3 and later. Turn it off if TARGET_FPU is
disabled.
(sparc_rtx_costs): Handle 'FMA'.
* doc/invoke.texi: Document -mfmaf.
