[PATCH] Allow paren casted throw statements inside of ternary expressions

[Richard Smith]

Please also add a test that IRGen copes with this when it appears as a
condition (for instance, on the LHS of another ?: operator) -- we have
special handling for that which has had problems with throw-expressions in
the past. Otherwise, LGTM, thanks!
