54fde020cc Enable Java on Cygwin-64
Currently it is not possible to build GCC's libjava support on Cygwin-64.

This patch fixes the current build-problems on Cygwin-64 and the most
fundamental bugs on that platform.

Note you must still add --enable-threads=posix to successfully build the
java language support.

	(_Jv_ResolvePoolEntry): Use METHOD_NOT_THERE and METHOD_INACCESSIBLE.
	(_Jv_DetermineVTableIndex): Ditto.

	pointer of new object before returning.
	(_Jv_AllocBytes): Use GC_MALLOC_ATOMIC, not GC_GENERIC_MALLOC.
