  tcg/arm: Fix double-word comparisons

The code sequence we were generating was only good for unsigned
comparisons.  For signed comparisions, use the sequence from gcc.

Fixes booting of ppc64 firmware, with a patch changing the code
sequence for ppc comparisons.

  -----------
  tcg/ppc: Allow a 32-bit offset to the constant pool

We recently relaxed the limit of the number of opcodes that can
appear in a TranslationBlock.  In certain cases this has resulted
in relocation overflow.
