There are only 'skip'ped commits left to test.
The first bad commit could be any of:

We cannot bisect more!
bisect run cannot continue any more

    mesa: Drop unused SFL/STR opcodes.

    They're part of NV_vertex_program2, which I'm pretty sure we're never
    going to support.

    mesa: Drop unused NV_fragment_program opcodes.

    The extension itself was deleted 2 years ago.  There are still some
    prog_instruction opcodes from NV_fp that exist because they're used by
    ir_to_mesa.cpp, though.
