31f78c4f6b 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.

6d78311fd2 Added functions to compute which register, if any, to use
for a particular argument in a list of arguments.

dbc4fad577 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.

4876209aa6 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.

03d33bd264 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.

76d12299b5 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.

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.

7a716added Changes to:
* Fix bug printing method types (oops when converting previous code)
* Move some of the code from Constant::getStrValue implementations here.
  This allows us to do a MUCH MUCH better job printing out complex constant
  values (think an array of structure pointers), because we print symbolic
  type names instead of structural.  The assistance when debugging is immense

Eventually, Constant::getStrValue should be removed (it existed before because
the asmwriter file was not in VMCore), and everyone should go through the
asmwriter that want's equivalent functionality.
