cmd/internal/obj/arm: fix constant decomposition
There are two issues in constant decomposition.
1. A typo in "func immrot2s" blocks "case 107" of []optab be triggered.
2. Though "ADD $0xffff, R0, R0" is decomposed to "ADD $0xff00, R0, R0" and
"ADD $0x00ff, R0, R0" as expected, "ADD $0xffff, R0" still uses the
constant pool, which should be the same as "ADD $0xffff, R0, R0".
This patch fixes them and adds more instruction encoding tests.
fix #20516
