[Mesa-dev] [PATCH v3 04/14] glsl: remove duplicate validation for index layout qualifier

[Timothy Arceri]

From: Timothy Arceri <timothy.arceri at collabora.com>

The minimum value for index is validated in the ast code and
we want to remove validation from the parser so we can add
compile time constant support.
