aarch64: Relax some builtins to AUTO_FP

Browse Source 
This patch relaxes the flags for some builtins to AUTO_FP. These
builtins do permutes and similar, so they shouldn't get the FP flags
when operating on floating-point modes as they don't care about
FPCR/FPSR and exceptions.

gcc/ChangeLog:

	* config/aarch64/aarch64-simd-builtins.def (combine, zip1, zip2,
	uzp1, uzp2, trn1, trn2, simd_bsl): Use AUTO_FP flags.
