d6373bcd82 Fix a bug in SelectScalarSSELoad. Since the load is wrapped in a 
SCALAR_TO_VECTOR, even if the hasOneUse() check pass we may end up folding
the load into two instructions. Make sure we check the SCALAR_TO_VECTOR
has only one use as well.

4eab71497d add an initial cut at preinc loads for ppc32. This is broken for ppc64 
(because the 64-bit reg target versions aren't implemented yet), doesn't
support r+r addr modes, and doesn't handle stores, but it works otherwise. :)

This is disabled unless -enable-ppc-preinc is passed to llc for now.

fef02427cd completely revert patrick's enhancement to bugpoint. Though it makes bugpoint 
speed up, it sometimes makes it crash on complex bc files, which isn't very nice.


With this, bugpoint can reduce the 176.gcc failure.

cd6f46e2ac add a new bugpoint mode -llc-safe. This uses LLC for both halves of a 
miscompilation.  This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.
