6dc46fce5a 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().

too!

a63a20d3eb Removed linking functionality from gccld.cpp and moved it to linker.cpp. 
Renamed functions that were all lower-case.
Moved functions from util.cpp into linker.cpp or gccld.cpp.
Removed util.h and created gccld.h.
Refactored the linker functionality in linker.cpp so that it is easier to
follow, easier to modify, and it's library/object file search behavior is
easier to understand and document.
Added code to include library paths when doing native linking, but this
causes problems and is currently #ifdef'd out.

7a032bd1de Changed the empty rule for .h files. The rule needs an empty command so that 
Make actually uses it to "regenerate" header files that have been
moved/removed.

b22c819f96 Fix (and properly doxygenify) some comments. Incorporate 
functionality of FunctionInfo pass as doFinalization method.
Rename pass to match names of other passes like it.

e1ccc5a286 In ExecWait(), made the child process exit if it can't execve() the new
