I forgot that we always spill fp values as 64-bits. Implement spill folding
...
for FP as well. This triggers a couple dozen times on 177.mesa (for example).

Fix a problem that Nate noticed, where spill code was not getting coallesced
...
with copies, leading to code like this:
lwz r4, 380(r1)
or r10, r4, r4 ;; Last use of r4
By teaching the PPC backend how to fold spills into copies, we now get this
code:
lwz r10, 380(r1)
wow. :)
This reduces a testcase nate sent me from 1505 instructions to 1484.
Note that this could handle FP values but doesn't currently, for reasons
mentioned in the patch

Minor cleanups:
...
* avoid calling getClass() multiple times (it is relatively expensive)
* Allow -disable-fp-elim to turn of frame pointer elimination.
