Rounding differences between 1.8 and 1.7 (including -Xint mode).

[Dawid Weiss]

Hi everyone.

We observe test regressions on fairly complex computational code
resulting from small differences in double roundings. They show up
when executed with latest 1.8 snapshot (compared to 1.7 and 1.6). Also
applies when run in interpreted mode (-Xint).

I was wondering if this is something to be expected? Thanks,

Dawid
