SVE intrinsics: Fold constant operands for svmul.
This patch implements constant folding for svmul by calling
gimple_folder::fold_const_binary with tree_code MULT_EXPR.
Tests were added to check the produced assembly for different
predicates, signed and unsigned integers, and the svmul_n_* case.
The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
OK for mainline?
