We let a lot of "non-standard" values be visible, so that we can make
sense of them in interface pragmas. It's cool, though they all have
"non-standard" names, so they won't get past the parser in user code.

+%************************************************************************
+
+These are Ids that we need to reference in various parts of the
+system, and we'd like to pull them out of thin air rather than pass
+them around. We'd also like to have all the IdInfo available for each
+one: i.e. everything that gets pulled out of the interface file.
+
+The solution is to generate this map of global Ids after the
+typechecker, and assign it to a global variable. Any subsequent
+pass may refer to the map to pull Ids out. Any invalid
+(i.e. pre-typechecker) access to the map will result in a panic.
