70a6a4b463 OK, after checking the backwards compatibility code on X86 and the new code 
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.

ed49a51836 Fix bug 537 test 2, which checks to make sure that we fold A+(B-A) -> B for 
integer types.  Add a couple checks to not perform these kinds of transform
on floating point values.
