deqp/functional/gles3/shadercommonfunction.html fails on Mac AMD

Project Member Reported by zmo@chromium.org, Sep 3 2016

Issue description

There are two issues

1) roundEven(-0.5) returns 0 instead -0.  The test verifies it should be -0, however, I can't seem to find spec text to support this.  From the spec, it seems 0 is acceptable.

2) int(true) incorrectly return a number different from 1.
For this issue, I added conformance/glsl/bugs/bool-type-cast-bug.html

Also, when fixing this bug, please run the full regression test:

Maybe the Mac Intel workaround can also be applied to Mac AMD?  crbug.com/650547
