This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Tblgen doesn't like multiple SDNode<> definitions that map to the sameenum value.  Split them into separate enums.

Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

* Added a pseudo instruction (for each target) that represent "return void".
