Previously we used an i32 constant to store the saturation width, but i32 isn't legal on RISCV64. This wasn't a big deal to fix, but it is extra work for the type legalizer. This patch uses a VTSDNode to store the type similar to SEXT_INREG. This makes it opaque to the type legalizer. Reviewed By: nikic Differential Revision: https://reviews.llvm.org/D101262
