LoongArch: Remove unneeded "andi offset, addr, 3" instruction in atomic_test_and_set
On LoongArch sll.w and srl.w instructions only take the [4:0] bits of
rk (shift amount) into account, and we've already defined
SHIFT_COUNT_TRUNCATED to 1 so the compiler knows this fact, thus we
don't need this instruction.
gcc/ChangeLog:
* config/loongarch/sync.md (atomic_test_and_set): Remove
unneeded andi instruction from the expansion.
