e513b0ead4 refactor(library,hott): rename theorems for decidable and inhabited 
The convention is this: we use e.g. nat.is_inhabited and nat.has_decidable_eq
for these two purposes only, to avoid clashing with "inhabited" and "decidable_eq"
in a namespace. Otherwise, we use "decidable_foo" and "inhabited_foo".

d1ba9ba1dd feat(hott/types/sigma): simplify file using 'cases' tactic, definitional package and rewrite tactic 
Simpler version is also faster.
On my notebook, the runtime was 2.8 secs before, and 1.1 secs after changes

It replaces the commands: class, instance, coercion, multiple_instances,
reducible, irreducible

d2958044fd feat(frontends/lean): add multiple_instances command 
After this commit, Lean "cuts" the search after the first instance is
computed. To obtain the previous behavior, we must use the new command
