tcg-arm: fix qemu_ld64
Emulating fldl on arm doesn't seem to work too well. It's the way
qemu_ld64 is translated to arm instructions.
tcg_out_ld32_12(s, COND_AL, data_reg, addr_reg, 0);
tcg_out_ld32_12(s, COND_AL, data_reg2, addr_reg, 4);
Consider case where data_reg==0, data_reg2==1, and addr_reg==0. First load
overwrited addr_reg. So let's put an if (data_ref==addr_reg).
