dcb90780 - [clang][index] Skip over `#include UNDEF_IDENT` in single-file-parse mode (#135218)

[clang][index] Skip over `#include UNDEF_IDENT` in single-file-parse mode (#135218) In the 'single-file-parse' mode, seeing `#include UNDEFINED_IDENTIFIER` should not be treated as an error. The identifier might be defined in a header that we decided to skip, resulting in a nonsensical diagnostic from the user point of view.
