re PR target/40741 (code size explosion for integer comparison)

* config/arm/arm.c (thumb1_rtx_costs): IOR or XOR with
a small constant is cheap.
* config/arm/arm.md (andsi3, iorsi3): Try to place the result of
force_reg on the LHS.
(xorsi3): Likewise, and split the XOR if the constant is complex
and not in Thumb mode.
