    intel/fs: Stop stack allocating large arrays

    Normally, we haven't worried too much about stack sizes as Linux tends
    to be fairly friendly towards large stacks.  However, when running DXVK
    apps under wine, we're suddenly subject to Windows' more stringent stack
    limitations and can run out of space more easily.  In particular, some
    of the shaders in Elite Dangerous: Horizons have quite a few registers
    and the arrays in split_virtual_grfs are large enough to blow a 1 MiB
    stack leading to crashes during shader compilation.
