Bug #20294: Parser no longer warns on some duplicated keys
https://bugs.ruby-lang.org/issues/20294#change-108469

* Author: kddnewton (Kevin Newton)
* Status: Closed
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
Previously, the parser would warn on all duplicated keys. Now some cases are not handled:

```ruby
{ 100.0 => 1, 1e2 => 1 }
{ 100.0 => 1, 1E2 => 1 }
{ 100.0 => 1, 100.00 => 1 }
{ 100.0r => 1, 100.00r => 1 }
{ 100.0i => 1, 100.00i => 1 }
```
