Description:
ARM: Fix a number of issues with running without VFPv3 support

The type recording binary operations stub contained a number of issues which
broke V8 when running without VFPv3 supoort.

1. The order of the high/low words of doubles in core register pairs where wrong
2. Missing allocation of a heap number for the result
3. Missing call to runtime

Added the option for printing the double values in register pairs to the
simulator.
