rts: Work around missing prototypes errors

Darwin's toolchain inexpliciably claims that `write_barrier` and friends
have declarations without prototypes, despite the fact that (a) they are
definitions, and (b) the prototypes appear only a few lines above. Work
around this by making the definitions proper prototypes.

Support large stack frames/offsets in GHCi bytecode interpreter

Bytecode instructions like PUSH_L (push a local variable) contain
an operand that refers to the stack slot. Before this patch, the
operand type was SmallOp (Word16), limiting the maximum stack
offset to 65535 words. This could cause compiler panics in some
cases (See #22888).

This patch changes the operand type for stack offsets from
SmallOp to Op, removing the stack offset limit.

Fixes #22888

JS: support levity-polymorphic datatypes (#22360,#22291)

- thread knowledge about levity into PrimRep instead of panicking
- JS: remove assumption that unlifted heap objects are rts objects (TVar#, etc.)

Doing this also fixes #22291 (test added).

There is a small performance hit (~1% more allocations).

Metric Increase:
