SVE intrinsics: Fold svaba with op1 all zeros to svabd.
Similar to
https://gcc.gnu.org/pipermail/gcc-patches/2024-October/665780.html,
this patch implements folding of svaba to svabd if op1 is all zeros,
resulting in the use of UABD/SABD instructions instead of UABA/SABA.
Tests were added to check the produced assembly for use of UABD/SABD,
also for the _n case.
The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
OK for mainline?
