For now, the elf writer is only capable of emitting an empty elf file, with
a section table and a section table string table.  This will be enhanced
in the future :)

should be able to handle this case.  The code is there, so let's see
if it works.

make AliasAnalysis know that VAArg writes memory.  This is extremely conservative and should be fixed

prevent GCSE from forwarding stores to loads around vaarg.  This is uggly, and I am trying to fix the AliasInfo, as it should catch the problem instead.

so this doesn't crash when run.  It is hard to tell if things are right enough to work correctly with all the TmpInstructions running around

path on alpha, now has come the time for new vararg support.  So, with out
further ado, I revert behavior back a couple of years!

Well, ok, I lied.  A few more notes.

First, the Simple ISels cannot be expected to work any longer, but they
should still compile

Second, there are likely some bugs to track down once the nightly testers
start with this.

Third, the initial patch doesn't include sparcv9, but I'll do that today.

Forth, subsequent patches won't bother being long winded.
