Leonardo de Moura 42fbe3c18c chore(library/init,runtime,library/compiler): add fix primitive back 
The new `partial def`s allow us to define `fix` in Lean, but the Lean
implementation is not as efficient as the native one. The native one
in C++ use weak pointers to prevent a closure allocation at every
recursive invocation.

This commit also fixes the `fixCore` helper functions that were broken
after we switched to camelCase.

We have updated the test `fix1.lean` to demonstrate the native
implementation is faster. Here are the numbers on my desktop.

```
./run.sh fix1.lean 24
721420279
Time for 'native fix': 816ms
721420279
Time for 'fix in lean': 1.34s
```
