Fix two significant bugs in LSR:
...
1. When rewriting code in outer loops, sometimes we would insert code into
inner loops that is invariant in that loop.
2. Notice that 4*(2+x) is 8+4*x and use that to simplify expressions.
This is a performance neutral change.

Two changes:
...
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.

ret int %C

_rlwnm:

rlwnm r2, r2, r3, 4, 17 ;; note the immediates :)

Fix a nasty problem on two-address machines in the following situation:
...
store EAX -> [ss#0]
[ss#0] += 1
...
use(EAX)
In this case, it is not valid to rewrite this as:
store EAX -> [ss#0]
EAX += 1
store EAX -> [ss#0] ;;; this would also delete the store above
...
use(EAX)
... because EAX is not a dead at that point. Keep track of which registers
we are allowed to clobber, and which ones we aren't, and don't clobber the
ones we're not supposed to. :)
This should resolve the issues on X86 last night.
