[aarch64/match.pd] Fix ICE observed in PR110280.
gcc/ChangeLog:
PR tree-optimization/110280
* match.pd (vec_perm_expr(v, v, mask) -> v): Explicitly build vector
using build_vector_from_val with the element of input operand, and
mask's type if operand and mask's types don't match.
gcc/testsuite/ChangeLog:
PR tree-optimization/110280
* gcc.target/aarch64/sve/pr110280.c: New test.
