The attached code (IsWeirdness.{cc,i}) produces the correct result when compiled
with -O2 -finline-functions on ia64 and with -O3 on alpha, but produces the
incorrect result with -O3 on ia64, which leads me to the conclusion that
something's gone all funny with -frename-registers on ia64.

The code is a bit nonsensical, as I've reduced it as much as possible while
preserving the incorrect behavior, but it should print the number "-764".  With
-O3 on ia64, it prints "-528".
