If we have a dmat2[4], then dmat2[0] is at 17, dmat2[1] at 19,
dmat2[2] at 21 etc. The old code was returning 17,18,19.
I think this code is also wrong for float matricies as well.
This partly fixes:
GL41-CTS.vertex_attrib_64bit.limits_test

There are some lines that exceed 80 chars in this file but this seems
way too long (?) You could put this case in braces and have a temporary
for glsl_type or maybe matrix cols to make it fit. Otherwise seems
correct to me. Looks like this has been broken for quite a long time,
even before program interface query was introduced.
