Applicative commutative cuts in Fixpoint guard condition
In "(match ... with |... -> fun x -> t end) u", "x" has now the subterm
property of "u" in the analysis of "t".
Commutative cuts aren't compatible with typing so we need to ensure that
term of "x"'s type and term of "u"'s have the same subterm_spec.
Consequently,declaration.MRec argument has changed to the inductive name
instead of only the number of the inductive in the mutual_inductive
family.
In subterm_specif and check_rec_call, arguments are stored in a stack.
At each lambda, one element is popped to add in renv a smarter
subterm_spec for the variable. subterm_spec of constructor's argument
was added this way, the job is now done more often.
Some eta contracted match branches are now accepted but enforcing
eta-expansion of branches might be anyway a recommended invariant.
