nasty issue where the x86 backend started miscompiling stuff in a 'cvs up'd
build after the altivec intrinsics were added.

visitBr to just call visitSwitchCase, eliminating duplicate logic.

Rename LHSBB/RHSBB to TrueBB/FalseBB.  Allow the RHS value to be null,
in which case the LHS is treated as a bool.

will be able to fall into it, do so.  Otherwise, put it in a place it can fall
through into a successor.  Otherwise, if preventing a fallthrough, move to the
end of the function, out of the way.

This deletes several hundred unconditional branches from spass.
