    mesa: increase the relative address offset limit to 4096 in ARB_vp/fp

    Even though the spec says that the limits should be -64/+63, proprietary
    drivers support much larger relative offsets and some applications do
    depend on this non-standard behavior.

    Also program_parse.tab.c has been regenerated.

    This fixes the parser error:

      ARB_vp: error: relative address offset too large

    See also: https://bugs.freedesktop.org/show_bug.cgi?id=28628

    4096 * sizeof(vec4) is the maximum size of the constant buffer on NV50.
    It is not supposed to be a definite hardware limit, it is for the parser
    not to get in the way and let the underlying driver decide whether it can
    run the shader or not.
