Fixing that requires adjustment to several points where we used this for array indexing, and two places that develop -Wswitch warnings after the change.

Drop the special case, previously used, where the input is already zero-extended -- the minor code size savings is not worth the complication.

Pass the ct mask instead of the whole TCGArgConstraint, as that's the only part that's relevant. Change the value argument to int64_t. We will need the extra width for 32-bit hosts wanting to match vector constants.

This duality causes warnings on GCC 11 and prevents build using --enable-werror. As second version provides more information, unify functions prototypes to this variant.

That is, the conversion rules are as: (common_type) c2 == (common_type) (uint32_t) (is_unsigned ? (uint32_t)c2 : (uint32_t)(int32_t)c2) In the signed case we lose the desired sign extensions because of the argument promotion rules of the ternary operator. Solve the problem by doing the round-trip parsing through the intermediate type and back to the desired common type (all at one expression).
