  Log Message:
  -----------
  Reland "[PowerPC] set libcall lowering for fp setcc ops on SPE boards" (#199198)

This is a reland of 4d0100789dc9b4db7d77c033d8f53f8b7dc68437, which was
reverted by c24ab4c814f680c5ac71600bf80d551123abd84d.

The functionality is unchanged from the original patch. This version
only fixes the fast-math flag propagation issue by passing `SDNodeFlags`
explicitly to `DAG.getSetCC()` (same as #199105 which was closed because
the underlying patch had been reverted).
