Rework build_switch to use initialize_def.

This required support for label reference expressions, whose purpose is to
represent the address of a label.

Bring back the unsigned type (PROGS version bump)

This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

Unfortunately, this seems to overdo the decrementing, so it could be
dangerous, but the ruamoko directory builds properly.

Don't let casting in constfold increment users.
...
This fixes Deek's temp notice. No new notices have shown up, so this should
be the correct fix. The constant folding code no longer calls cast_expr
directly, but rather uses an internal wrapper that decrements users after
cast_expr increments it, resulting in a no-op.

that particular error case is a type mismatch rather than an internal error. found when trying to compare a SEL with a string... oops :)
