[Mesa-dev] [PATCH v4 10/20] clover: Track flags per module section

[Pierre Moreau]

One flag that needs to be tracked is whether a library is allowed to
received mathematics optimisations or not, as the authorisation is given
when creating the library while the optimisations are specified when
creating the executable.

Notes:
    Changes in v4: drop the modification to the tgsi backend, as already dropped
