JDK 9 RFR of JDK-8139688 Port fdlibm exp to Java

[Brian Burkhalter]

Hi Joe,

This looks fine to me. I’ve just a few picayune items:

1. FdLibm

Line 649: I assume the weird “halF” (upper case F) is retained in order to match the original C code.

2. TEST.ROOT

Line 30: The jtreg required version is reverted.

3. ExpTests

Lines 65 and 69: The threshold values in comments could be static final constants as well as they are used at lines
66, 70, 109 and 112.

Thanks,

Brian
