The SH backend has permanently enabled its Long-Range Addresser (LRA) register allocator, addressing PR target/55212. The -mlra option is now ignored but kept for compatibility, and the TARGET_LRA_P macro has been removed. This change signifies LRA as the default and only register allocation strategy for SH targets.
