1. Not selecting the false value of a select_cc in the false arm, which
isn't legal for nested selects.
2. Actually returning the node we created and Legalized in the FP_TO_UINT
Expander.

codegen for FP_TO_UINT by using the legalizer's SELECT variant.
Implement a codegen improvement for SELECT_CC, selecting the false node in
the MBB that feeds the phi node. This allows us to codegen:
void foo(int *a, int b, int c) { int d = (a < b) ? 5 : 9; *a = d; }
as:
_foo:
li r2, 5
cmpw cr0, r4, r3
bgt .LBB_foo_2 ; entry
.LBB_foo_1: ; entry
li r2, 9
.LBB_foo_2: ; entry
stw r2, 0(r3)
blr
insted of:
_foo:
li r2, 5
li r5, 9
cmpw cr0, r4, r3
bgt .LBB_foo_2 ; entry
.LBB_foo_1: ; entry
or r2, r5, r5
.LBB_foo_2: ; entry
stw r2, 0(r3)
blr

specified opcode and an integer constant right operand.
2. Modified ISD::SHL, ISD::SRL, ISD::SRA to use rlwinm when applied after a mask.

the CC handling logic throughout the ISel.

1. Clean up how SelectIntImmediateExpr handles use counts.
2. "Subtract from" was not clearing hi 16 bits.

Includes wider support for rotate and mask cases.
Patch by Jim Laskey.
I've requested that Jim add new regression tests the newly handled cases.

depending on the command line option. Now the command line option just
sets the subtarget as appropriate. G5 opts will now default to on on
G5-enabled nightly testers among other machines.

Remove the LoadHiAddr pseudo-instruction.
Optimization of stores to and loads from statics.
Force JIT to use new non-PIC codepaths.

This is the last MVTSDNode.
This allows us to eliminate a bunch of special case code for handling
MVTSDNodes.
Also, remove some uses of dyn_cast that should really be cast (which is
cheaper in a release build).

1. Pass Value*'s into lowering methods so that the proper pointers can be
added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
into any load/stores from the valist that are emitted

is at least overloading the right virtual methods. The implementations
are currently wrong though. This fixes Ptrdist/bc, but not other programs
(e.g. siod).

avoids dereferencing the end() iterator when selecting the fallthrough
block. This requires an ilist change.
