Devang Patel db789fb8f2 Implement PassManagerImpl_New::add(). 
Just add pass into the pass manager queue without processing analysis.

Devang Patel 90b05e0bc3 While adding pass into the manager, process Analysis only if it is 
required to do so.

Reid Spencer 279a3aefc3 Enable path completion when typing the TESTSUITE= option by allowing the 
test directory to precede the test suite name. That is, it will strip off
test/ from TESTSUITE which allows path completion from the command line.

Chris Lattner a0a8003f59 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.

Devang Patel 6c9f548704 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.

Chris Lattner d4dee405cb Fix InstCombine/2006-11-10-ashr-miscompile.ll a miscompilation introduced

Evan Cheng 49683ba236 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.

Evan Cheng fb44822a98 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.

Chris Lattner ce6455489a 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.

Anton Korobeynikov b9c91c265c Fixing PR990: http://llvm.org/PR990. 
This should unbreak csretcc on Linux & mingw targets. Several tests from
llvm-test should be also restored (fftbench, bigfib).
