Chris Lattner ff0c8a7511 This checkin represents some cleanup of the backend, implementing the following things:
1. The TargetMachine structure is free to decide the process a particular target uses to generate code.
2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory.  The Sparc.h file that is globally visible is just a stub.
3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort.


NOTE! The BBLiveVar.cpp file dependant on the Sparc backend, and is therefore not generic/portale to other backends.  This needs to be fixed.

Vikram S. Adve 1143eff628 analyze() now checks to see that we don't analyze the same method twice.
Needs a mechnanism to override this check (e.g., after a transformation).

Chris Lattner 81f3ace753 IntervalPartition was changed to inherit from vector<Interval*> instead of
contain it so that it would have full iterator access without much work.

Writer includes code to print out IntervalPartition's now.
