  Log Message:
  -----------
  RuntimeLibcalls: Emit all available impls for a libcall, not just one (#210915)

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.
