[PATCH 2/2] aarch64: Adjust predicate used for SVE2 SHA3 XAR rotate amount

[Kyrylo Tkachov]

Hi all,

While fixing the Advanced SIMD XAR patterns I looked at SVE2 and
it looks okay there but the rotate amount should use the
aarch64_simd_rshift_imm predicate rather than lshift_imm since the
instruction (unlike the Advanced SIMD version) takes values from
[1, bitwidth].

Bootstrapped and tested on aarch64-none-linux-gnu.
Will push as obvious together with the first patch.
Thanks,
Kyrill

        aarch64_simd_rshift_imm predicate for rotate amount.
