    testsuite: Add -mtune=generic to dg-options for two testcases.
    
    Use -mtune=generic to limit these two test cases. Because configuring them with
    -mtune=cascadelake or znver3 will vectorize them.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/costmodel/x86_64/costmodel-pr104582-2.c: Add
            -mtune=generic to dg-options.
            * gcc.target/i386/pr84101.c: Likewise.
