Summary: PowerPC64: Allow swift three element aggregate results
in fast isel
Product: libraries
Version: trunk

Allow swift three element aggregate results in fast isel
When bootstrapping swift on PowerPC64, I hit a number of failures:
Return operand #2 has unhandled type i64
Swift wants to create three element aggregates, but that fails in fast isel.
The attached patch fixes it, but I'm not sure if this is safe.
There are other swift ABI differences we have to model, so there will have to
be another calling convention for swift at some stage.
