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

patterns. This allows emission of this code:

move %icc, %i0, %i2

restore %g0, %g0, %g0
retl

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

This should fix a bunch of tests - anyone have any comments, though?

Size and Alignment do now?
- in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and

distinguish between 'size' and 'spillsize' etc. hmm.

Use Evan's outflag stuff to implement V8cmpicc. This allows us to write a
...

an instruction in the common "setcc X, imm" case.

* Add special entry code main() (to set x87 to 64-bit precision).
...
* Allow a register node as SelectAddr() base.
* ExternalSymbol -> TargetExternalSymbol as direct function callee.
* Use X86::ESP register rather than CopyFromReg(X86::ESP) as stack ptr for
call parmater passing.
