Description
libfontmanager in JDK is  built with default compiler optimisation flags.
By increasing it to a higher level as used on most other libraries, some 
tests which attemp to exercise some of that native code can run 5-20% faster
on Windows and Solaris.
This particularly will help cases where complex text layout is used as that uses
a significant amount of native C++ code in libfontmanager.
There is a small increase in disk footprint - amounting to just about 30Kbytes
on Windows 32 bit but this is presumably also in line with what is already happening
in all other libs.
