First step towards V9 instructions in the V8 backend, two conditional move

patterns. This allows emission of this code:
t1:
save -96, %o6, %o6
subcc %i0, %i1, %l0
move %icc, %i0, %i2
or %g0, %i2, %i0
restore %g0, %g0, %g0
retl
nop
instead of this:
t1:
save -96, %o6, %o6
subcc %i0, %i1, %l0
be .LBBt1_2 !
nop
.LBBt1_1: !
or %g0, %i2, %i0
.LBBt1_2: !
restore %g0, %g0, %g0
retl
nop
for this:
int %t1(int %a, int %b, int %c) {
%tmp.2 = seteq int %a, %b
%tmp3 = select bool %tmp.2, int %a, int %c
ret int %tmp3

Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it
...
faster. This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).
It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change. Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.
This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.

Several major changes:
...
1. Pull out the expand cases for BSWAP and CT* into a separate function,
reducing the size of LegalizeOp.
2. Fix a bug where expand(bswap i64) was wrong when i64 is legal.
3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be
iterative. It now operates in a single pass over the nodes.
4. Simplify a LOT of code, with a net reduction of ~280 lines.
