  Log Message:
  -----------
  RuntimeLibcalls: Emit all available impls for a libcall, not just one

The intent is RuntimeLibcalls should represent all functions that are
callable from the module, which may have contextually selectable alternatives.
Previously we had this warning since there was no mechanism to select which
one you want, and as a workaround the library call sets avoided adding the
variants which should nto be selected.

Now targets can use initLibcallLoweringInfo, so remove the warning to unblock
more libcall cleanups. Eventually initLibcallLoweringInfo should also be tablegen
driven.
