Log Message:
-----------
Stop parsing on first syntax error.
We try to keep parsing after many types of errors, up to a (current)
maximum of 10 errors. Continuing after a semantic error (like
undeclared variables) can be helpful, for instance showing a set of
common errors, but continuing after a syntax error isn't helpful
most of the time and will produce sometimes completely bizarre errors
which just obscure the actual error most of the time.
This patch makes the parser stop after the first syntax error, while
preserving the current behavior for other errors. An error is considered
a syntax error if the error message from our internals is the literal
text "syntax error". This may not be a complete list of true syntax
errors, we can iterate on that in the future.
