917 * The reason for this hack is to fix the behavior of inflating generic methods that come from a MethodBuilder.
918 * What happens is that instantiating a generic MethodBuilder with its own arguments should create a diferent object.
919 * This is opposite to the way non-SRE MethodInfos behave.
921 * This happens, for example, when we want to emit a recursive generic method. Given the following C# code:
923 * void Example<T> () {
927 * In Example, the method token must be encoded as: "void Example<!!0>()"
929 * The reference to the first generic argument, "!!0", must be explicit otherwise it won't be inflated
930 * properly. To get that we need to inflate the MethodBuilder with its own arguments.
932 * On the other hand, inflating a non-SRE generic method with its own arguments should
933 * return itself. For example:
935 * MethodInfo m = ... //m is a generic method definition
936 * MethodInfo res = m.MakeGenericMethod (m.GetGenericArguments ());
939 * To allow such scenarios we must allow inflation of MethodBuilder to happen in a diferent way than
940 * what happens with regular methods.
942 * There is one last touch to this madness, once a TypeBuilder is finished, IOW CreateType() is called,
943 * everything should behave like a regular type or method.

2999 * Most classes implement a very small number of interfaces, so the bitmap is
3000 * sparse. This bitmap needs to be checked by interface casts, so access to the
3001 * needed bit must be fast and doable with few jit instructions.
3003 * The current compression format is as follows:
3004 * *) it is a sequence of one or more two-byte elements
3005 * *) the first byte in the element is the count of empty bitmap bytes
3006 * at the current bitmap position
