target/loongarch: Fix qemu-loongarch64 hang when executing 'll.d $t0, $t0, 0'
On gen_ll, if a->imm is zero, make_address_x return src1,
but the load to destination may clobber src1. We use a new
destination to fix this problem.
Fixes: c5af6628f4be (target/loongarch: Extract make_address_i() helper)
