The m2n wrapper marshals HandleRef structs from a vtype to intptr. The MonoMethod for a pinvoke method stores the unmarshalled signature. When locating the args on the stack during the pinvoke call we need to use the marshalled signature instead (which is saved in the code stream for the calli opcode)
