Hi,

This patch uses the new builtin-mapping infrastructure
to map the fcvt family of builtins directly to their
GCC standard pattern name.

Regression tested on aarch64-none-elf with no regressions.

Thanks,
James

	* config/aarch64/aarch64-builtins.c
	(aarch64_builtin_vectorized_function): Use new names for
	fcvt builtins.
	* config/aarch64/aarch64-simd-builtins.def (fcvtzs): Split as...
	(lbtruncv2sf, lbtruncv4sf, lbtruncv2df): ...This.
	(fcvtzu): Split as...
	(lbtruncuv2sf, lbtruncuv4sf, lbtruncuv2df): ...This.
	(fcvtas): Split as...
	(lroundv2sf, lroundv4sf, lroundv2df, lroundsf, lrounddf): ...This.
	(fcvtau): Split as...

	(lfrintnv2sf, lfrintnv4sf, lfrintnv2df, lfrintnsf, lfrintndf): New.
	(lfrintnuv2sf, lfrintnuv4sf, lfrintnuv2df): Likewise.
	(lfrintnusf, lfrintnudf): Likewise.
	* config/aarch64/aarch64-simd.md
	(l<fcvt_pattern><su_optab><fcvt_target><VDQF:mode>2): Convert to
	define_insn.
