Jacob Gravelle 37af00e7d0 [WebAssembly] Narrow the scope of WebAssemblyFixFunctionBitcasts
Summary:
The pass to fix function bitcasts generates thunks for functions that
are called directly with a mismatching signature. It was also generating
thunks in cases where the function was address-taken, causing aliasing
problems in otherwise valid cases.
This patch tightens the restrictions for when the pass runs.
