Type of programs in common/AST made more dependent.
In particular, the type of internal functions is now dependent on the
list of global variables. This is already used in the back-end to rule
out from the syntax programs that have free variables.
Note: only the test Clight/test/search.c.ma has been ported to the new type.
The porting requires two very minor changes.
