the same functionality.  This addresses another piece of bug 680.  Next,
on to fixing Alpha VAARG, which I broke last time.

Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

amount handling that PPC provides.  These are generated by the lowering code
and prevents the dag combiner from assuming (rightfully) that the shifts
don't only look at 5 bits.  This fixes a miscompilation of crafty with
the new front-end.

on Darwin to remove smarts from the isel.  This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file.  However, we can currently emit stuff like
this:  :)

        li r2, lo16(L_x$non_lazy_ptr)
        lis r3, ha16(L_x$non_lazy_ptr)
        lwzx r2, r3, r2

The obvious improvements will follow.

allows us to lower legal return types to something else, to meet ABI
requirements (such as that i64 be returned in two i32 regs on Darwin/ppc).

such as the PowerPC 970.

This speeds up 189.lucas from 81.99 to 32.64 seconds.

giving it a non-instruction opcode.  The dag->dag selector used to not
select the operands of the fsel, because it thought that whole tree was
already selected.

instead of in the backend.  This currently handles fsel cases with registers,
but doesn't have the 0.0 and -0.0 optimization enabled yet.

Once this is finished, special hack for fp immediates can go away.
