simplify-rtx: Push sign/zero-extension inside vec_duplicate
As a general principle, vec_duplicate should be as close to the root
of an expression as possible. Where unary operations have
vec_duplicate as an argument, these operations should be pushed
inside the vec_duplicate.
This patch modifies unary operation simplification to push
sign/zero-extension of a scalar inside vec_duplicate.
This patch also updates all RTL patterns in aarch64-simd.md to use
the new canonical form.
gcc/ChangeLog:
2021-07-19 Jonathan Wright <jonathan.wright@arm.com>
* config/aarch64/aarch64-simd.md: Push sign/zero-extension
inside vec_duplicate for all patterns.
* simplify-rtx.c (simplify_context::simplify_unary_operation_1):
Push sign/zero-extension inside vec_duplicate.
