Define the instance variable Buffer, not the automatic variable Buffer.
This was causing us to munmap random stuff, which is obviously bad.

If we fail to find python or qmtest, give a warning message instead of an
error message.  This should hopefully allow our nightly tester to run, which
does not run the QMTest tests at present.

Suggestions made by Chris:
* Instead of a #define, use inline function
* Fix the name on the #define, errr... now inline function to be more logical:
  it doesn't CHECK the alignment, it PERFORMS the alignment
* To get string name of a Type*, use getDescription(), not getName()

* Make sure we align the buffer we're given
* Do not let exceptions propagate when the caller asks for a Module*
* Add doxygenified comments to wrapper functions

I tried to standardize the formatting and tidy up the huge amount of
excess whitespace a little. Also improved some comments.

Convert PhyRegAlloc into a proper pass.

PhyRegAlloc.cpp:
 Don't include TargetMachine.h or TargetRegInfo.h, because these are provided
  by PhyRegAlloc.h.
 Merge class RegisterAllocator into class PhyRegAlloc.
 Simplify & move ctor, dtor to PhyRegAlloc.h.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 MarkAllocatedRegs() becomes a member method, with fewer args.

PhyRegAlloc.h:
 Include Pass.h, TargetMachine.h and TargetRegInfo.h. Don't declare
  TargetRegInfo forward.
 Give AddedInstrns the obvious clear() method.
 Make some of PhyRegAlloc's reference members into pointer members,
  so they can be more easily messed with.
 Add prototype for markAllocatedRegs().
 Remove unused inline void constructLiveRanges().

Switch from using CallInst's to represent call sites to using the LLVM
CallSite class.  Now we can represent function calls by invoke instructions
too!
