    Adjust testcase.
    
    This testcase is used to detect reuse of perm mask in the main loop,
    in epilog, vpermi2b can still be used, so add the option
    --param=vect-epilogues-nomask=0.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/i386/pr82460-2.c: Adjust testcase by adding
            --param=vect-epilogues-nomask=0
