--- Comment #1 from Antia Puentes <apuentes at igalia.com> ---
This should be fixed now.

The commit originating the regressions was reverted by me, however, in issue 
https://github.com/KhronosGroup/OpenGL-API/issues/32 it was clarified that the
commit implemented the correct behaviour.

Commit is now restored in Mesa master and the regressions fixed in Piglit.

    mesa: add missing RGB9_E5 format in _mesa_base_fbo_format

    RGB9_E5 should be accepted by RenderbufferStorage if the
    EXT_texture_shared_exponent is exposed. It is left to the
    implementations to return GL_FRAMEBUFFER_UNSUPPORTED_EXT
    when checking the framebuffer completeness if they do not
    support rendering in this format.

    Discussed in:
    https://github.com/KhronosGroup/OpenGL-API/issues/32

    This fixes KHR-GL45.internalformat.renderbuffer.rgb9_e5

    v2: Added more info to the commit message (Antia)

    internalformat_query*: fix SAMPLES pname checks for RGB9_E5

    SAMPLES and NUM_SAMPLE_COUNTS queries accept internalformats which
    are defined as color-, depth- or stencil-renderable. RGB9_E5 is marked
    as non color-renderable in OpenGL 4.6, however if the
    EXT_texture_shared_exponent extension is exposed it must be considered
    as such. The later was discussed in:
    https://github.com/KhronosGroup/OpenGL-API/issues/32

    v2: use 'tex' as shortname for texture instead of 'text' (Piñeiro)
