Description:
A64: Rejig truncating and non double to i/smi
Replace existing DoubleToI/DoubleToSmi instructions with truncating and non-
truncating versions. This allows reuse of common code, register constraints
and environment requirements.
Also, use new JumpIfMinusZero function in DoNumberUntagD to remove
unimplemented
code tag.
