[PATCH] D131990: [DRAFT][WebAssembly] Do not support `[[clang::musttail]]` by default

[Thomas Lively via Phabricator via cfe-commits]

tlively added a comment.

For reference, the existing error from the backend is something like this:

  test.cpp:9:5: error: WebAssembly 'tail-call' feature not enabled
  int foo(int x) {
      ^

Note that it points to the beginning of the callee rather than the specific line containing the tail call.

Ideally we would get the current fatal error and diagnostic message with the more specific context from this patch.
