return std::auto_ptr and use exceptions

* 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()

llvm-svn: 8683

* 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

* Stop using a #define, make it an inline if statement

  because it can add a module ID which we do not have at this time.
* Check to see if the module has been initialized when materializing it.

  - no more passing around a string pointer to set errors
  - no more returning booleans and checking for errors, we use C++ exceptions
* Broke functionality into 2 new classes, one reads from file, one from a stream
* Implemented lazy function streaming - the parser can read in a function at-a-time

... by making sure to update PHI nodes to take into consideration the
extra edges we get if we inline a call instruction through an invoke.

 * Local header file goes at top
 * Remove unneeded #includes
 * Wrap code at 80 columns
 * Declare variables where they are used
 * 'register' is not needed
 * Use 'unsigned' instead of 'int' variables where possible

(I also zapped printMachineCode() and printLabel() at the previous checkin,
but forgot to mention it.)

Remove more excess whitespace.

llvm-svn: 8644

Fix typos in file header comment.

excess whitespace a little. Also improved some comments.

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().
