[PATCH] RISC-V: testsuite: Add rv64 requirement for bug-9 and bug-14.

[Robin Dapp]

Hi,

this adds an effective target requirement to compile the tests.  Since
we disabled 64-bit indices on rv32 targets those tests should be
unsupported on rv32.

Regards
 Robin

gcc/testsuite/ChangeLog:

        * g++.target/riscv/rvv/base/bug-14.C: Add
        dg-require-effective-target rv64.
        * g++.target/riscv/rvv/base/bug-9.C: Ditto.
