Subject: Perform function lifting and inlining in arch plugins

This change allows architecture plugins to override the LiftFunction
callback to iterate a function's basic block list and lift entire
functions at once. This is required for architectures such as TMS320
C6x, which have non-traditional "delay slots" in that branches, loads,
and other instructions take multiple cycles to complete, and branch
instructions can reside within the delay slots of other branches.
