[PATCH] RISC-V/testsuite: Enable `vect_pack_trunc'

[钟居哲]

             || ([istarget mips*-*-*]
                 && [et-is-effective-target mips_msa])
+            || [istarget riscv*-*-*]
             || ([istarget s390*-*-*]
                 && [check_effective_target_s390_vx])
              || [istarget amdgcn*-*-*] }}]

You should change it into:

|| ([istarget riscv*-*-*]
     && [check_effective_target_riscv_v])

Then, these additional FAILs will be removed:

with no changes (except for intermittent Python failures for C++) with the 
remaining testsuites.  There are a few of regressions in `-march=rv64gc'
