Subject: [PATCH 064/157] [Backport][SME] aarch64: Make AARCH64_FL_SVE
 requirements explicit

Reference: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=dd7aaef62a43efe52eece525eea4d7d252b0c148

So far, all intrinsics covered by the aarch64-sve-builtins*
framework have (naturally enough) required at least SVE.
However, arm_sme.h defines a couple of intrinsics that can
be called by any code.  It's therefore necessary to make
the implicit SVE requirement explicit.

gcc/
	* config/aarch64/aarch64-sve-builtins.cc (function_groups): Remove
	implied requirement on SVE.
	* config/aarch64/aarch64-sve-builtins-base.def: Explicitly require SVE.
	* config/aarch64/aarch64-sve-builtins-sve2.def: Likewise.
