Remove simple JS->Wasm entry thunks by using metadata
https://bugs.webkit.org/show_bug.cgi?id=267481
rdar://120933304
Reviewed by Yusuke Suzuki.
This patch lays the groundwork for a new way to call wasm functions without JIT.
We opt in only the simplest cases for now, but in those cases, we can skip the
generated JS->WASM entry thunk. Future work can expand this to more signatures.
This also changes the way tier-up works. Today, we re-write the JS->Wasm
entrypoint
call pointer. This won't work anymore, so we instead check when loading the
entrypoint
for interpreted-entry callees.
This shouldn't affect the jsCallEntrypoint IC, so this is a step in the
direction
of completely removing these non-ic jit thunks in the future.
