79ce276083 Move a few containers out of ScheduleDAGInstrs::BuildSchedGraph 
and into the ScheduleDAGInstrs class, so that they don't get
destructed and re-constructed for each block. This fixes a
compile-time hot spot in the post-pass scheduler.

To help facilitate this, tidy and do some minor reorganization
in the scheduler constructor functions.

b1b5ffd827 Added a more function PIC16 backend. However to get this working a patch in 
ExpandIntegerOperand (LegalizeIntegerTypes.cpp) is needed which is yet to be reworked and submitted.
