perf(library/local_context): fix performance bottleneck at local_const
...
This is one of the performance problems at issue #1646 .
The method `local_context::erase_user_name(local_decl const & d)` was
inefficient when there are many locals with the same user facing name.
For size 7 in the example described at issue #1646 , the average size of the
declaration list was 400. Here are the runtimes for size 7
Before: 19.021 secs
After: 16.433 secs
There are more performance issues.

fix(library): change API and make sure we don't crash when searching for a non existing local decl
...
Fixes #1363
After error recovery has been implemented in the elaborator, a few
assumptions made in the type context are not valid anymore since we may
be recovering from errors, and the local and metavariable contexts may
be invalid.
I used the approach used in the class environment.
- find* methods return optional<...>
- get* methods throw exception for unknown elements
Remarks:
I preserved code patterns such as
optional<local_decl> d = lctx.find_local_decl(...)
lean_assert(d)
and did not convert them into
local_decl d = lctx.get_local_decl(...)
Reason: the intention is clear that the local must be defined there.
If it is not we should analyze the problem and decide whether we should
throw an exception or not.
However, I converted code patterns such as
local_decl d = *lctx.find_local_decl(...)
into
local_decl d = lctx.get_local_decl(...)
Disclaimer: this change fixes issue #1363 , but it may obfuscate other bugs.
