  Log Message:
  -----------
  [Clang] Fix eager skipping in `ParseExpressionList()` (#110133)

i.e., in a call like `function(new Unknown);` the parser should skip only until the
semicolon.

Before this change, everything was skipped until a balanced closing
parenthesis or brace was found. This strategy can cause completely bogus
ASTs. For instance, in the case of the test `new-unknown-type.cpp`,
`struct Bar` would end nested under the namespace `a::b`.
