* Add a useful file comment
* Move InsertPrologEpilogCode class to PrologEpilogCodeInserter.cpp
   -> Among other things, this eliminates the need for the minstrVec static
      global array.

Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the
new PrologEpilogCodeInserter.cpp file, and include the bodies of the

into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.
