87f92ec32d [WebAssembly] Reapply r319186: "Support bitcasted function addresses with varargs."
This puts the functionality under control of a command-line option which is
off by default to avoid breaking existing setups.

5155d5128a [WebAssembly] Revert r319186 "Support bitcasted function addresses with varargs."
The patch broke Emscripten's EM_ASM macros, which utiltize unprototyped
functions.

See https://bugs.llvm.org/show_bug.cgi?id=35385 for details.

7005517f42 [WebAssembly] Support bitcasted function addresses with varargs.
Generalize FixFunctionBitcasts to handle varargs functions. This in
particular fixes the case where clang bitcasts away a varargs when
calling a K&R-style function.

This avoids interacting with tricky ABI details because it operates
at the LLVM IR level before varargs ABI details are exposed.

This fixes PR35385.
