glsl: add offset to glsl interface type
In this patch we also copy the offset value from the ast and
implement offset linking rules by adding it to the record_compare()
function.
From Section 4.4.5 (Uniform and Shader Storage Block Layout Qualifiers)
of the GLSL 4.50 spec:
"Two blocks linked together in the same program with the same block
name must have the exact same set of members qualified with
offset and their integral-constant-expression values must be the
same, or a link-time error results."
