[Mesa-dev] [PATCH shaderdb 1/3] run: split out helper to create contexts

[Matt Turner]

All three look good to me. Thanks for doing this. It's been on my todo
list for a while.

The ES shaders we have in our internal shader-db have been working
because of ARB_ES*_compatibility, which I guess could be used to avoid
some API switches, but that only worked out more or less by accident
in the current code.
