The vrgather.vv instruction uses a vector of indices with the same SEW as operand 0. The vrgather.vx instructions use a scalar index operand of XLen bits. By splitting this into 2 intrinsics we are able to use LLVMatchType in the definition to avoid specifying the type for the index operand when creating the IR for the intrinsic. For .vv it will match the operand 0 type. And for .vx it will match the type of the vl operand we already needed to specify a type for. I'm considering splitting more intrinsics. This was a somewhat odd one because the .vx doesn't use the element type, it always use XLen. Reviewed By: HsiangKai Differential Revision: https://reviews.llvm.org/D95979
