1bff0f0174 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.

ae1f3758bd 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.

3a017e8abd 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.

1604b6a873 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.

This should unbreak csretcc on Linux & mingw targets. Several tests from
llvm-test should be also restored (fftbench, bigfib).
