I ran the patch on several benchmarks to check performance, overall the changes look good, but there is a regression in one of the benchmarks (EEMBC/coremark-pro) caused by creating an undesired lea instruction instead of the previously created add instruction, I am working on creating a simple reproducer for the problem and would appreciate your patience.
