Code review request for 4900206 "Include worst-case rounding tests for Math library functions"

Hello. Cleaning up my bug backlog, please review the addition of some new math library tests: 4900206 "Include worst-case rounding tests for Math library functions" http://cr.openjdk.java.net/~darcy/4900206.0/ These tests probe at hard to round values generated by number-theoretic techniques. I've verified the tests pass on Linux x86 and Solaris sparc. Thanks, -Joe
