Description
With the transition to gradle some of the compiler flags used to build JFX native libraries changed.
For example, decora-sse used to use -Ox, now that changed to -O2.

We need to investigate any performance impact caused by these changes.
Comments
I don't think we will get anything from these compiler flags I'm testing but I'm keeping this bug open till I can test on a 64 bit machine.

I tested -Ox, fp:fast, arch:sse for prism-common on Windows 8, 32bits and I didn't see meaningful performance improvement running DiamondBenchmarkCanvas, which makes heavy use of NativePiscesRasterizer. I don't have results running a 64bit VM as mysteriously Java8 crashes on my machine when executing gradle, decora compiler, etc
