	ebee5b3b	2017-11-23T12:56:32		Add GLSL support for runtime-sized arrays in SSBOs The GLSL parser now allows a runtime-sized array as the last member in a shader storage block. Clamping indexing against the memory bounds is done by determining the array length at runtime. Runtime-sized arrays are used in dEQP tests for many compute shader tests, so these now work on the OpenGL backend.

	bb5a7e29	2017-08-30T13:03:12		Allow length() on arbitrary array expressions This is required to pass some dEQP GLES 3.1 tests for arrays of arrays, and WebGL conformance tests were also recently fixed to require this behavior. The intent of the GLSL ES spec was not to restrict usage of length(). In practice GL drivers don't implement array length() on expressions with side effects correctly in all cases. HLSL doesn't have an array length operator either. Because of this we always remove array length ops from the AST before output.
