[MRISC32] Not getting scaled index addressing in loops

Hello! I maintain a fork of GCC which adds support for my custom CPU ISA, MRISC32 (the machine description can be found here: https://github.com/mrisc32/gcc-mrisc32/tree/mbitsnbites/mrisc32/gcc/config/mrisc32 ). I recently discovered that scaled index addressing (i.e. MEM[base + index * sca
