Summary: GCC compresses the pseudo instruction "mv rd, rs", which is an alias of "addi rd, rs, 0", to "c.mv rd, rs". In LLVM we rely on the canonical MC instruction (MCInst) to do our compression checks and since there is no rule to compress "addi rd, rs, 0" --> "c.mv rd, rs" we lose this compression opportunity to gcc. In this patch we fix that by adding an addi to c.mv compression pattern, the instruction "mv rd, rs" will be compressed to "c.mv rd, rs" just like gcc does. Patch by Zhaoshi Zheng (zzheng) and Sameer (sabuasal).
