Prepare HotSpot for the permissive- Visual C++ flag, this change contains all of the fixes required for HotSpot to compile under the stricter mode activated when the permissive- flag is passed
- Reworks code in topLevelUnhandledExceptionFilter for os_windows.cpp to avoid goto jumping across uninitialized locals
- Adds a CAST\_FROM\_FN\_PTR cast to the return value from ::signal to void, as they cannot be implicitly converted
- symbolengine.cpp's SimpleBufferWithFallback's templates cannot work with a raw char (Actual fix under discussion)
- Removed a throw() specification from a mismatched definition in allocation.cpp
