[Mesa-dev] [PATCH] mesa: remove OES_shader_io_blocks enable

[Ilia Mirkin]

This extension should just be available whenever ES 3.1 is available.
With the new extension verification infrastructure, it will only be
enable-able on a #version 310 es shader, rendering the original reason
for having a separate enable moot.
