Yes.

BEGV, PT, etc. are covered by the "Buffer Internals" node, except that
they are lowercased there (because they describe the corresponding
struct members to which the upper-cased macros expand).

CHECK_FOO just checks that the Lisp_Object is of type FOO.  This is
useful when you need to be sure you get the arguments of the right
type before you process them.
