    RISC-V: Fix two testscases related to -std changes.
    
    Recent -std changes caused testsuite failures.  Fix those by adding
    -std=gnu99 and -Wno-incompatible-pointer-types.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/pr112552.c: Add
            -Wno-incompatible-pointer-types.
            * gcc.target/riscv/rvv/autovec/struct/struct_vect_run-10.c:
            Add -std=gnu99.
