    match.pd: Fix up (X & Y) CMP 0 -> X CMP2 ~Y simplifications [PR104499]

    The following testcase ICEs on x86_64-linux, because match.pd emits
    there a NOP_EXPR cast from int*8 vector type with BLKmode to
    unsigned*8 vector type with BLKmode and vec-lowering isn't prepared
    to handle such casts.

    Fixed by using VIEW_CONVERT_EXPR instead.
