5c851091e5 Added functions to compute the offset of a given incoming or outgoing 
argument. These are no longer allocated as they are discovered.

ae709134c9 Optional args are no longer allocated as they are discovered. 
(This can be improved to avoid making the initial pass over the method.)
Also, ensure automatic vars and reg. spills areas are not extended
if their sizes are used for computing some other offset.

95b080aca1 Don't record instructions for copying method arguments in the 
AddedInstrns sets for the first machine instruction.  It is hard
to ensure that the right order is preserved, and sure enough, the
order was broken.  Instead, use a separate set for the function entry.

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.

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.

* Actually check that an instruction does not have a name if it has a void
  return type.

ded2679ed0 Make sure that there is no case where a signal can occur leaving a partially 
written output file.  This is important because crashing testcases often write
part of a file out, and the testing harness decides the file is up-to-date next
time the test is run.

f1dee31d23 Pull all of the getStrValue implementation cruft out of Constants.cpp and 
put it into the AsmWriter.  This code is kinda gross and could probably be
cleaned up, but not now.

bfad09f50d Remove getStrValue method from Constant implementations. The AssemblyWriter 
now knows how to write out a constant, not the constants themselves.  This is
fixed due to the move of the AsmWriter to the VMcore library.

a392a80a60 Significantly rework InstructionCombining to work better and to be cleaner. 
We now use an InstVisitor to delegate to different cases that we are
interested in handling.  We also fix the FIXME's by adding users to the
worklist when appropriate.

  instances of BinaryOperator for example.
