Series aarch64: Add support for SVE2.1 | expand

Commit Message

Richard Sandiford Nov. 6, 2024, 6:25 p.m. UTC 
Previous patches are supposed to add full support for SVE2.1,
so this patch advertises that through __ARM_FEATURE_SVE2p1.

pragma_cpp_predefs_3.c had one fewer pop than push.  The final
test is triple-nested:

- armv8-a (to start with a clean slate, untainted by command-line flags)
- the maximal SVE set
- general-regs-only

gcc/
	* config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Handle
	__ARM_FEATURE_SVE2p1.

gcc/testsuite/
	* gcc.target/aarch64/pragma_cpp_predefs_3.c: Add SVE2p1 tests.
