(which died about a week ago) so we're back to load-(2^n-1)-then-AND
sequences. slow, but things should now be Almost Completely Working,
modulo those pesky alignment/ABI issues.

instruction defined, actually emit this to the InstrInfoDescriptor, which
allows an assert in the machineinstrbuilder to do some checking for us,
and is required by the dag->dag emitter

I'm not convinced this is all of them,  but I can't do much testing, because
IA64 LLC crashes on big programs :(

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.

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.
