Subject: Globalenvs: allocate one-byte block with permissions Nonempty for
 each   function definition, so that comparisons between function pointers  
 are correctly defined. AST, Globalenvs, and many other files:   represent
 programs as a list of (function or variable) definitions   instead of two
 lists, one for functions and the other for variables.
