1004ba9d5f Don't pad spills and temp. stack areas for alignment. 
Freeze auto vars and spill areas when their sizes are used
for computing other offsets.

a9037d5d60 Major changes to how int and FP arguments are handled. Varargs 
function calls were simply wrong; other functions were just not
using all available registers.

10ba17d6fe Added functions to compute which register, if any, to use 
for a particular argument in a list of arguments.

9995ae21c2 Insert copy operations for FP arguments to a varargs function, 
to copy the FP arg. to an integer.  Necessary so that the
register allocator has two different live ranges for the FP value
and the int. argument.

dbc90d1c0c * Add a useful file comment

   -> Among other things, this eliminates the need for the minstrVec static
      global array.

259b748661 Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the 
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.
