Timothy Flynn eb74781a2d LibJS: Keep the lookahead lexer alive after parsing its next token 
Currently, the lexer holds a ByteString, which is always heap-allocated.
When we create a copy of the lexer for the lookahead token, that token
will outlive the lexer copy. The token holds a couple of string views
into the lexer's source string. This is fine for now, because the source
string will be kept alive by the original lexer.

But if the lexer were to hold a String or Utf16String, short strings
will be stored on the stack due to SSO. Thus the token will hold views
into released stack data. We need to keep the lookahead lexer alive to
prevent UAF on views into its source string.
