PR target/44757
* config/lm32/lm32.h (LEGITIMATE_CONSTANT_P): Call
lm32_legitimate_constant_p.
* config/lm32/lm32.md (ashlsi3): Remove unused variable.
* config/lm32/lm32.c (gen_int_relational): Make new block for
LE / LT / LEU / LTU case. Declare variables at start of block.
(lm32_block_move_inline): Use XALLOCAVEC.
