Yes,  as Juzhe said I had run all the riscv regression, but without RTL check. I will fix it.
Sorry for forgetting to enable RTL checking for testing.
Thanks Juzhe for helping me reverse this commit.

We (me and kito) has reviewed vector-crypto.

I believe Wang Feng has done && passed the regression (with no RTL check), but he just didn't enable RTL check I guessed.
(By default, RTL check is disabled in riscv-gnu-toolchain, developers need to enable it manually).

It's ok to revert the patch, then commit it after he fixes the ICE with enabling RTL check.

So let's just revert it, it doesn't even look like it was reviewed.  
We've set a really bad precedent here where we're just merging a bunch 
of unreviewed code and sorting out the regressions in trunk, that's not 
the right way to do things.
