address of the PassInfo directly instead of calling getPassInfo.
This eliminates a bunch of dynamic initializations of static data.

Also, fold RegisterPassBase into PassInfo, make a bunch of its
data members const, and rearrange some code to initialize data
members in constructors instead of using setter member functions.

Teach X86 a few more vsetcc patterns.  Custom lowering for unsupported ones is next.

merging will not add an extra branch in this case.

semantically identical, but little difference in
either results or execution speed; but it's much
easier to read, at least IMO.

Hard code CmpInst back to i1 for now while I go track down what in the bitcode reader/writer is assuming i1
This was breaking a bunch of tests

Also fixes the -Wall option handling as a side-effect.
