move_operand is general_operand minus some types of operands containing
symbol_refs that aren't valid.  Since FP operands will never contain
symbol addresses, in theory, the use of move_operand instead of
general_operand is extra unnecessary overhead.

By the way, I added fr_spill to the list of patterns that I am fixing.
I am convinced I have the complete list now.

I have started a full build and test, but I have two patches to test and
one machine to test them on, so it will take me a while.
