Conversation
This commit inlines fast paths for the `{enter,exit}_sync_call` component
trampolines in sync-to-sync fused adapters. For cross-component calls of trivial
functions, after inlining, we should avoid all calls in the fused adapter (other
than the `trap` libcall when `may_leave` is set).
The inlining happens during translation, rather than via the regular inliner,
since the lazy thread is stack-allocated within the fused adapter; there would
otherwise be no easy way to reference it.
Fixes bytecodealliance#12311
