Long double patch 8 of N: make it partially work in
...
SSE mode (all but conversions <-> other FP types, I think):
>>Do not mark all-80-bit operations as "Requires[FPStack]"
(which really means "not SSE").
>>Refactor load-and-extend to facilitate this.
>>Update comments.
>>Handle long double in SSE when computing FP_REG_KILL.

For PR786:

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Rewrite FP stackifier support in the X86InstrInfo.td file, splitting patterns
...
that were overloaded to work before and after the stackifier runs. With the
new clean world, it is possible to write patterns for these instructions: woo!
This also adds a few simple patterns here and there, though there are a lot
still missing. These should be easy to add though. :)
See the comments under "Floating Point Stack Support" for more details on
the new world order.
This patch as absolutely no effect on the generated code, woo!
