41e53fd39b disallow preinc of a frameindex. This is not profitable and causes 2-addr
pass to explode.  This fixes a bunch of llc-beta failures on ppc last night.

a363a0bdef Keep track of analysis required by the passes. Force use of new pass
manager if a pass does not preserve analysis that is used by other
passes.

8ca29326e1 Don't dag combine floating point select to max and min intrinsics. Those
take v4f32 / v2f64 operands and may end up causing larger spills / restores.
Added X86 specific nodes X86ISD::FMAX, X86ISD::FMIN instead.

This fixes PR996.

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.
