I timed one long-running test and the elapsed time became 2/3 of that
without -O2.
I than ran the entire W3C test suite. There was only one difference:

< <v toobig="yes">1.9345000000000003E+122</v>

> <v toobig="yes">1.9344999999999999E+122</v>

Since there are already differences on this test case with the W3C
expected results, and these are only floating point rounding
differences, I am happy, and will check in the change.
