glsl/linker: outputs in the same location must share auxiliary storage

From ARB_enhanced_layouts:

"[...]when location aliasing, the aliases sharing the location
  must have the same underlying numerical type (floating-point or
  integer) and the same auxiliary storage and
  interpolation qualification.[...]"

Add code to the linker to validate that aliased locations do
have the same aux storage.

all three tests also fail on Nouveau. So it could be, that I will work on this
sooner or later. Will add it to my todo list with no guarantee when I can
actually start to work on it. At some point next month or later, depending on
whatever comes up and how much time I will have for CTS stuff.
