This patch implements constant folding for svmul. If the predicate is
ptrue or predication is _x, it uses vector_const_binop with
aarch64_const_binop as callback and tree_code MULT_EXPR to fold constant
integer operands.
Tests were added to check the produced assembly for different
predicates, sign
