glsl-1.30: add test for default in switch not after all case statements

By the looks of it "default" is not required to appear as last statement
in a switch expression, and c rules should be followed (which is probably
a mess to implement thanks to fallthrough).
Seems to fail with mesa glsl compiler (at least with tgsi translation).
