target-mips: Remove unused gen_load_ACX, gen_store_ACX and cpu_ACX

Remove the functions gen_load_ACX and gen_store_ACX, which appear to have
been unused since they were first introduced many years ago. These functions
were the only places using the cpu_ACX[] array of TCG globals, so remove
that and its accompanying regnames_ACX[] as well.
