Implement truncated d-to-i as a stub on x86

- Added a general DoubleToIStub so that it's possible to extend to other platforms and non-truncating case.
- This version handles all cases of truncation (previous code deopted in some cases) and all source/destination register combinations without clobbering any temps.
