I've bisected it to:

    mesa: refactor active attrib queries for glGetProgramiv

    Main motivation here is to get rid of iterating IR and
    encapsulate queries within program resources.
    No functional changes.

    Piglit tests calling the modified functionality:

       - gl-get-active-attrib-returns-all-inputs
       - glsl-1.50-get-active-attrib-array
       - getactiveattrib

When I revert 'a563689' all is smooth, again.
