From OpenGL ES 3.0 spec, page 56:
"Binding more than one attribute name to the same location
is referred to as aliasing, and is not permitted in OpenGL
ES Shading Language 3.00 vertex shaders. LinkProgram will
fail when this condition exists. However, aliasing is
possible in OpenGL ES Shading Language 1.00 vertex shaders.
This will only work if only one of the aliased attributes
is active in the executable program, or if no path through
the shader consumes more than one attribute of a set of
attributes aliased to the same location. A link error can
occur if the linker determines that every path through the
shader consumes multiple aliased attributes, but implemen-
tations are not required to generate an error in this case."
So here we make sure to allow the optimisations before validation
for earlier ES shader versions.
