Alexander Markov 16e8dc257e [vm] Faster double.floor()/ceil()/truncate() in AOT mode (x64, arm64) 
1) double.truncate() now simply calls toInt(), omitting
truncateToDouble() call.

2) double.floor() and ceil() are now intrinsified on arm64 and AOT/x64
and generated using DoubleToInteger instruction.

3) DoubleToInteger instruction is extended to support floor and ceil.
On arm64 DoubleToInteger is implemented using fcvtms and fcvtps
instructions. On x64 DoubleToInteger is implemented using roundsd
under a check if it is supported (with a fallback to a stub and a
runtime call).

AOT/x64:
Before: BenchFloor(RunTime): 318.82148549569655 us.
After:  BenchFloor(RunTime): 133.29430189936687 us.
