WebAssembly requires caller and callee signatures to match exactly. In LLVM, there are a variety of circumstances where signatures may be mismatched in practice, and one can bitcast a function address to another type to call it as that type. This patch adds a pass which replaces bitcasted function addresses with wrappers to replace the bitcasts. This doesn't catch everything, but it does match many common cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@291315 91177308-0d34-0410-b5e6-96231b3b80d8
