[PATCH v2 0/3] target/riscv: corner case fixes

[Nicholas Piggin <npiggin@gmail.com>]

Changes:
v1->v2:
* Added a tcg tests build-time check for vector intrinsics support
  in target compiler before building new tests that require it.
  ci images may not support these yet unfortunately, but upgrading
  those will be a separate effort.

There is ongoing effort to run generated test verification on the 
QEMU riscv CPU which has turned out a few corner cases.

I added some fixes for these, as well as tcg tests. The
interrupted vector test also catches a bug in
"Generate strided vector loads/stores with tcg nodes." that
I referred to in the v5 thread for that series.

Thanks,
Nick
