[PATCH] D77633: [Parser] Improve diagnostic and error recovery when C++ keywords are used as identifiers.

[Johannes Doerfert via Phabricator via cfe-commits]

This is cool, thx!

One case I stumbled upon recently is:
`void explicit() {}`

Which results in these rather confusing messages:

  /tmp/test.cpp:1:14: warning: explicit(bool) is a C++20 extension [-Wc++20-extensions]
  void explicit() { }
               ^
  /tmp/test.cpp:1:15: error: expected expression
  void explicit() { }
                ^
  /tmp/test.cpp:1:17: error: expected unqualified-id
  void explicit() { }
                  ^
  1 warning and 2 errors generated.

Just in case you want to continue this ;)
