Please review the small fix for jdk9.
The change add an additional gcc option to the libawt lib to improve some graphics operations: 20%.

This option is a part of -03.
> -fgcse-after-reload
>  <>When -fgcse-after-reload is enabled, a redundant load elimination pass is performed after reload. The purpose of this pass is to clean up redundant spilling.

Note that if -03 will be enabled directly via OPTIMIZATION flag then the performance will not be improved.
