Make the PPC backend not dependent on BRTWOWAY_CC and make the branch
selector smarter about the code it generates, fixing a case in the
readme.

Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

Lower GOT relative addresses to Lo and HI.
Update both ISels to select them when they can.
Saves instructions here and there.

Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)

Though I have done extensive testing, it is possible that this will break
things in configs I can't test.  Please let me know if this causes a problem
and I'll fix it ASAP.
