- Register scavenger should use MachineRegisterInfo and internal map to find the first use of a register after a given machine instruction.
- When scavenging a register, in addition to the spill, insert a restore before the first use.
- Abort if client is looking to scavenge a register even when a previously scavenged register is still live.

This doesn't have a significant impact on most code yet because it doesn't
yet do anything to address anti-dependencies and it doesn't attempt to
disambiguate memory references. Also, several popular targets
don't have pipeline descriptions yet.

The majority of the changes here are splitting the SelectionDAG-specific
code out of ScheduleDAG, so that ScheduleDAG can be moved to
libLLVMCodeGen.a. The interface between ScheduleDAG-using code and
the rest of the scheduling code is somewhat rough and will evolve.

from the object to the function (reference/pointer) and the
conversions in the arguments.

Use PreprocessorLexer::getFileID() instead of Lexer::getFileLoc().  This is an intermediate step to having getCurrentLexer() return a PreprocessorLexer* instead of a Lexer*.
