Lowering priority, since this requries the --wasm-lazy-compilation command line flag.

Can this check failure have security consequences, if not, please change Type=Bug-Security to Type=Bug

[wasm] Remove obsolete DCHECKS

HeapConstant in the code.
This CL just removes the DCHECKs, which failed with the
--wasm-lazy-compilation flag.
