Remove SRE.UnmanagedMarshal dependency from System.Reflection.

	* FieldInfo.cs:
	* MonoMethod.cs:
	* ParameterInfo.cs: Remove silly dep on UnmanagedMarshal to use
	MarshalAsAttribute which is what we need in the end.

	* icall.c:
	* reflection.c: Use the custom attribute type instead of the SRE
	one. This allows FULL_AOT_RUNTIME to work with stuff that uses
	MarshalAs.

Fix gdb backtraces on OSX.

We can't redirect output from gdb: since gdb will suspend us we won't
be able to read from the pipe we've redirected output to, and we'll
end up deadlocking if gdb outputs a lot of data (see bug mono#2548).

Disable gdb backtracing until mono#2548 has been fixed.
