Using is_conv rather than eq_constr to find `nat` or `Z` in omega.
Moving at the same to a passing "env sigma" style rather than passing
"gl". Not that it is strictly necessary, but since we had to move
functions taking only a "sigma" to functions taking also a "env", we
eventually adopted the "env sigma" style. (The "gl" style would have
been as good.)
This answers wish #4717.
