Give ADJCALLSTACKDOWN/UP the correct operands.

Give a whole bunch of other stuff variable operands, particularly FP. The
FP stackifier is playing fast and loose with operands here, so we have to
mark them all as variable. This will have to be fixed before we can dag->dag
the X86 backend. The solution is for the pre-stackifier and post-stackifier
instructions to all be disjoint.

When emitting implicit use/def lists, only emit each unique list once. Though
...
LLVM is able to merge identical static const globals, GCC isn't, and this caused
some bloat in the generated data. This has a marginal effect on PPC, shrinking
the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger
reduction.
This should speed up the register allocator as well by reducing the dcache
footprint for this static data.
