This patch introduces the pipeline description for the Synopsys RHX-100 series processor to the RISC-V GCC backend. The RHX-100 features a 10-stage, dual-issue, in-order execution pipeline architecture. Due to instruction fusion, up to four instructions can be issued in a single cycle; it is modeled as four separate pipelines, and the issue_rate is set to four.
