tcg/optimize: Introduce arg_const_val
Use arg_const_val instead of direct access to the TempOptInfo val
member. Rename both val and is_const to catch all direct accesses.

tcg/optimize: Introduce fold_masks_zosa
Add a new function with an affected mask. This will allow
folding to a constant to happen before folding to a copy,
without having to mind the ordering in all users.
