Remove stale disabled-test comments and re-enable already-fixed tests (#291)

Three TODO/disabled-test comments described bugs that were already fixed
(2026-07-05, see jit-globals-not-gc-roots and coro-dynamic-alloca-print-crash
history) but never got cleaned up:

- test-compile-Raytrace / test-jit-Raytrace: "TODO: find out why it is
  crashing" - fixed via GC_add_roots registration for JIT'd globals.
- test-compile-00-for-await-yield: was commented out entirely ("TODO: in opt
  mode, error") - fixed via heap-allocating string-concat scratch buffers
  inside presplit coroutines instead of a dynamic stack alloca. Re-enabled.
- test-jit-00-for-await-yield: had a stale comment describing the same
  now-fixed coroutine crash above an already-enabled, already-passing test.

817/817 tests green (816 + newly re-enabled test-compile-00-for-await-yield).
