aarch64: Simplify output template emission code for a few patterns
If the output code for a define_insn just does a switch (which_alternative) with no other computation we can almost always
replace it with more compact MD syntax for each alternative in a mult-alternative '@' block.
This patch cleans up some such patterns in the aarch64 backend, making them shorter and more concise.
No behavioural change intended.
Bootstrapped and tested on aarch64-none-linux-gnu.
gcc/ChangeLog:
* config/aarch64/aarch64-simd.md (*aarch64_simd_mov<VDMOV:mode>): Rewrite
output template to avoid explicit switch on which_alternative.
(*aarch64_simd_mov<VQMOV:mode>): Likewise.
(and<mode>3): Likewise.
(ior<mode>3): Likewise.
* config/aarch64/aarch64.md (*mov<mode>_aarch64): Likewise.
