* jit-icall.c (mono_object_castclass_with_cache): Check
        single entry cache before calling mono_object_isinst.

        * jit-icall.c (mono_object_isinst_with_cache): Check
        single entry cache before calling mono_object_isinst.
        This uses a positive and negative cache as it is used
        for type queries quite often.

        * jit-icalls.h: Export new icalls.

        * mini.c (mini_init): Register new icalls.

        * method-to-ir.c: Call into cache aware version of type
        test ops for types with variant generic arguments.

        This patch replaces direct calls to mono_object_castclass
        mono_object_isisnt to functions that check a cache first.
        The cache is per managed code callsite so the hit ratio
        is very high.

	* method-to-ir.c: Casts to generic types with variant argument
	can use the regular fast path if all variant arguments are
	valuetypes.

	* marshal.c (mono_marshal_load_type_info): Properly check for
	array types.

	-Dispose will call TransformFinalBlock() for Read streams. Fixes bug #644648.
	-Dispose () will call Dispose (bool). Fixes bug #644654.
	-Stream.Close calls GC.SuppressFinalize(). Fixes bug #644660.

	mono_metadata_memberref_is_method: rename to mono_memberref_is_method
	and deal with the case where the assembly is dynamic. This prevents
	a runtime crash when calling ModuleBuilder.ResolveMemberToken with
	a MemberRef token pointing to a field.

	mono_reflection_get_token: For FieldBuilders, now reuse the token
	computed when the FieldBuilder are instantiated, instead of
	re-creating them. This avoids registering field definitions
	as MemberRefs.

	We were previously relying on the runtime to register the token
	for FieldBuilders, but this has issues with fields on generics types
	as it would create a MemberRef token instead of a Field token.

Significant XamlObjectWriter rewrite for solid state transition. And now it supports Array(Extension) and other MarkupExtension types.

Avoid clearing nursery fragments before pinning, instead place arrays at the start of each fragment which cover the whole fragment.

Remove the MonoGenericContext/MonoMethod arguments from the get_this_arg () and get_unbox_trampoline () family of functions, they are no longer needed after the this parameter passing changes.

	This test failed to compile (internal error). Large changes required in
	?mcs before this can be compiled.

	The URL has been moved permanently. Use the raw format instead of
	downloading the HTML page.

	_GNU_SOURCE was redefined

	Use MONO_TYPE_BOOLEAN instead of MONO_NATIVE_BOOLEAN. Same value,
	different enums.

	X509Chain will now add the LM store certificates always, even when the
	CU store is selected.

Use MarkupExtension.ProvideValue() so that XamlObjectReader can return expected Result. Implement internal IXamlNameResolver for Reference resolution.
