remove some old hacky code that tried to infer whether a store
...
occured in a pattern, but failed miserably. The new code works for
any instruction that has a store in its pattern, including all the
x86 mem op mem instructions.
The only target-independent code that uses this is branch folding,
so this won't change anything in practice.

Emit real operand info for instructions. This currently works but is bad
...
in one way: the generated tables require dynamic initialization for the
register classes. This will be fixed in a future patch.

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.
