[Bug target/126196] The vsm3me.vv instruction (Zvksh, SM3 message expansion) is documented as a reserved encoding when the destination register group (vd) overlaps the first source register group (vs2). When compiling code that uses the __riscv_vsm3me_vv_u32m1 / __riscv_vsm3

--- Comment #3 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Given this is code generation correctness, I think it's a viable backport
candidate.  I'll let is soak on the trunk, likely until the Tues meeting at
which I'll backport assuming there haven't been any issues reported.
