Miika-Petteri Matikainen acd8a092f8 Make syntaxError suppressable (fixes #5917 and #7076)
syntaxErrors were not suppressable, because they were treated as
InternalErrors which were thrown and catched during the checking,
and normal suppression rules were not applied for those.

We fix this by calling the normal reportErr() function that does
suppression matching.
