    nir/alu_to_scalar: Use ssa_for_alu_src in hand-rolled expansions

    The ssa_for_alu_src helper will correctly handle swizzles and other
    source modifiers for you.  The expansions for unpack_half_2x16,
    pack_uvec2_to_uint, and pack_uvec4_to_uint were all broken with regards
    to swizzles.  The brokenness of unpack_half_2x16 was causing rendering
    errors in Rise of the Tomb Raider on Intel ever since c11833ab24dcba26
    which added an extra copy propagation to the optimization pipeline and
    caused us to start seeing swizzles where we hadn't seen any before.

    Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107926
    Fixes: 9ce901058f3d "nir: Add lowering of nir_op_unpack_half_2x16."
    Fixes: 9b8786eba955 "nir: Add lowering support for packing opcodes."
