Teach the interpreter to handle global variables that are added to a module after
...
interpretation has begun. The JIT already handles this situation correctly, and
the interpreter can already handle new functions being added.

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.
