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);...

Fix 64-bit targets compilation on ARM host.

Only fix compilation, probably doesn't run.

arm: Don't potentially overwrite input registers in add2, sub2.

According to malc TCG will often genereate an add2/sub2/mul2 with low
half of the output in the same register as high half of one of the
inputs, so account for that.

Don't rely on ARM tcg_out_goto() generating just a single insn.

Otherwise when tb_exit generates a jump beyond the pc-relative range,
tcg_out_goto() spans two/three instructions and we load the tb return
value from a wrong address. This is #ifdefed out currently because...

A branch insn must not overwrite the branch target before relocation.

When a branch to label is translated it generates a reloc that is filled in
when the label is translated. However, when handling an exception and
searching for the pc we abort the translation early and we sometimes...

Fix qemu_ld/st for mem_index > 0 on arm host.

offsetof(CPUState, tlb_table[mem_index][0].addr_read) with mem_index > 0
was larger than max immediate offset for ldr and str (12-bit) so insert an
additional insn to add the mem_index offset.

ARM host support for TCG targets.

Updated from previous version to use the tcg prologue/epilogue mechanism, may be slower than direct call.
