Fix that pesky floats in integer regs problem by assigning the f32 type to
...
the correct register class. Also remove the loading of float data into int
regs part of varargs; it will need to be implemented differently later.

Get closer to having varargs working. There's still something strange
...
going on with copies between floating point and integer register files
being generated. Once that is solved, varargs will be done.

Make 64bit args and float args work correct with calls. Thanks to Chris
...
for explaining EXTRACT_ELEMENT to me.

Support global addresses and fix call returns. Varargs still aren't
...
handled correctly for floating point arguments, or more than 8 arguemnts.
This does however, allow hello world to run.

Implement next round of Pattern ISel fixes
...
1. void returns
2. multiplies
3. calls

Implement more of the PPC32 Pattern ISel:
...
1) dynamic stack alloc
2) loads
3) shifts
4) subtract
5) immediate form of add, and, or, xor
6) change flag from -pattern-isel to -enable-ppc-pattern-isel
Remove dead arguments from getGlobalBaseReg in the simple ISel

Addition of the PPC32 Pattern ISel. While it is far from complete, it will
...
be brought up to parity with the current simple ISel in the coming days.
Currently, -pattern-isel is required to trigger it.
