SelectionDAG's topological sort in LegalizeDAG instead of having
a separate implementation.

where an appropriate reg-to-reg copy is not available.

assign it to a version of the xmm register with the regclass that matches its
type.  This fixes PR2715, a bug handling some crazy xpcom case in mozilla.

to actually be recycled. This cuts SelectionDAG's memory

Add a RetVT parameter to emitted FastISel methods, so that we will be able to pass the desired return
type down.  This is not currently used.

Expand bitcast support in fast isel to support bitcasts of non-constant values by emitting reg-reg copies.

Try approach to moving call address load inside of callseq_start. Now it's done during the preprocess of x86 isel. callseq_start's chain is changed to load's chain node; while load's chain is the last of callseq_start or the loads or copytoreg nodes inserted to move arguments to the right spot.
