Add FP support to the MacroAssembler, port JITArithmetic over to make use of this. Also add
API to determine whether FP support is available 'MacroAssembler::supportsFloatingPoint()',
FP is presently only supported on SSE2 platforms, not x87. On platforms where a suitable
hardware FPU is not available 'supportsFloatingPoint()' may simply return false, and all
other methods ASSERT_NOT_REACHED().
