    RISC-V: Testsuite fixes.
    
    This patch trivially fixes a few test cases that I noticed during
    testing.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/riscv/rvv/autovec/pr120378-1.c: Dump "optimized".
            * gcc.target/riscv/rvv/autovec/pr121510.c: Add semicolon.
            * gcc.target/riscv/rvv/base/pr112431-21.c: Add -Wno-pedantic.
    
    (cherry picked from commit 23a2cab0e68e8452014986fbdbb93df4eca3e0a2)
