7d054f8b3f The inst combining of inttoptr into GEP with one index was using the bit size of 
the type instead of the byte size. This was causing troublesome mis-compilations.

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

0b8b1647dd 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.

0f1c32eb63 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.

abf6c9aa1d Change PMTopLevelManager's PassManagers vector element type from 
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.

70f4b55e3f Change PMStack::push to accept a PMDataManager* instead of 
a Pass*. PMDataManager* is what it actually holds, so this
makes it clearer.
