Chris Willmore 42dba24464 Don't allow '{' at start of if-condition ...

If '{' is encountered immediately after 'if', assume that the condition
is missing. Apply the same treatment to while, do-while, for-in, and
switch. This way we're not trying to re-parse, backtrack, repurpose
misparsed closure bodies, etc. in those cases. Users who want to write a
condition that starts with '{' can wrap it in parens.
