[aarch64] Improve code-gen for vector initialization with single constant element.
gcc/ChangeLog:
* config/aarch64/aarch64.cc (aarch64_expand_vector_init): Tweak condition
if (n_var == n_elts && n_elts <= 16) to allow a single constant,
and if maxv == 1, use constant element for duplicating into register.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/vec-init-single-const.c: New test.
* gcc.target/aarch64/vec-init-single-const-be.c: Likewise.
* gcc.target/aarch64/vec-init-single-const-2.c: Likewise.
