User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0

Actual results:

conformance/glsl/misc/shaders-with-invariance.html (17 of 19 passed)

    failed: [unexpected link status] vertex shader with variant gl_Position and fragment shader with invariant gl_FragCoord must fail
    failed: [unexpected link status] vertex shader with variant gl_PointSize and fragment shader with invariant gl_PointCoord must fail


Expected results:

Chrome passes all the tests. Firefox fails the test with both the ANGLE and OpenGL backends.

Retested this today on my HASWELL PC with

Windows 10 Home 64-bit
3.0 GHz Intel 8-Core i7-5960X
32GB of RAM
3840x2160 pixels display

SLI 2x ASUS NVIDIA GeForce GTX 980 Ti, 4+4GB of VRAM, driver version 365.19
	- nvd3dumx.dll, nvwgf2umx.dll:
		- version 10.18.13.6191
		- date 2/8/2016
		- D3D Version 12.1, WDDM 2.0, WHQL approved

with Firefox Nightly 50.0a1 (2016-06-19), and I see the failure still occurs.
