Fix a number of encoding bugs. SSE 4.1 instructions MPSADBWrri, PINSRDrr, etc. have 8-bits immediate field (ImmT == Imm8).

True to form, this took 2 days to find and is a one-line fix. :-P

Livein copy scheduling fixes: do not coalesce physical register copies, correctly determine the safe location to insert the copies.

Don't try to sink 3-address instruction if convertToThreeAddress created more than one instructions.

TwoAddressInstructionPass enhancement. After it converts a two address instruction into a 3-address one, sink it past the instruction that kills the read-mod-write register if its definition is used past the kill. This reduces the number of live register by one.

Get rid of a pseudo instruction and replace it with subreg based operation on real instructions, ridding the asm printers of the hack used to do this previously. In the process, update LowerSubregs to be careful about eliminating copies that have side affects. 

Note: the coalescer will have to be careful about this too, when it starts coalescing insert_subreg nodes.

Pass* to PMDataManager*. PMDataManager is more specific than Pass,
so this more accurately describes the objects that are being stored.

This eliminates the need for several dynamic_casts to PMDataManager*.
It does introduce one dynamic_cast though, in dumpPasses(). Give
this one a comment describing why a dynamic_cast is being used.
