    RISC-V: Leverage stdint-gcc.h for RVV test cases
    
    Leverage stdint-gcc.h for the int64_t types instead of typedef.
    Or we may have conflict with stdint-gcc.h in somewhere else.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/unop/math-llrint-0.c: Include
            stdint-gcc.h for int types.
            * gcc.target/riscv/rvv/autovec/unop/math-llrint-run-0.c: Ditto.
            * gcc.target/riscv/rvv/autovec/unop/test-math.h: Remove int64_t
            typedef.

    (cherry picked from commit f0b05073bd3f0e5c8e55ef5a6fd16aa4518956a4)
