In riscv_vector_mode_supported_any_target_p we disallow any vector mode when TARGET_XTHEADVECTOR. Things go wrong when we check if a permutation for a mode is supported by just looking at the optab (e.g. in forwprop). Then later we try to expand that permutation but cannot find a related int vector mode because we don't allow any vector mode. Strictly speaking, this is fallout from the simplify_vector_constructor changes but it's still a target issue as the common code has done the proper check and we don't live up to the promise of being able to extend a certain mode. This patch just allows all modes in riscv_vector_mode_supported_any_target_p, even for theadvector.
