Currently, we were building an AST on document open or edit even if - `key_enablesyntaxmap` = 0 - `key_enablesubstructure` = 0 - `key_enablediagnostics` = 0 and - syntax tree transfer mode is off In those cases we were just ignoring the result. If all of the options are 0, don’t build an AST. rdar://85847659
