Final 8.1 development snapshot. Release candidate 0 will be next (after .NET 4.6 RTM).

Changes:

• Updated HOWTO reference to OpenJDK 8u45.
• Extract Windows version from kernel32.dll to avoid version lie. Idea stolen from OpenJDK.
• Moved unused field removal optimization to a later stage in the compilation.
• Made field removal optimization check more strict to only remove final fields and not remove fields that have annotations.
• Added support for automatically passing in fields to "native" methods.
• Various minor clean ups.
• Added FieldWrapper.IsSerialVersionUID property to properly (and consistently) detect serialVersionUID fields.
• Improved side effect free static initializer detection.
• Improved -removeassertions ikvmc optimization to remove more code (esp. allow otherwise empty static initializers to be optimized away).
