Richard Smith bdf54a21b5 PR18793: If we try to EnterTokenStream when our current lexer is a caching
lexer, add the token buffer underneath the caching lexer where possible and
push the tokens directly into the caching lexer otherwise. We previously
put the lexer into a corrupted state where we could not guarantee to provide
the tokens in the right order and would sometimes assert.
