<pre>Make ParserError immutable by design
https://bugs.webkit.org/show_bug.cgi?id=141955
Reviewed by Geoffrey Garen.
This patch enforce that no field of ParserError can
be modified after the constructor.
* parser/ParserError.h:
Move the attributes to pack the integer + 2 bytes together.
This is irrelevant for memory impact, it is to remve a load-store
when copying by value.
Also move the attributes to be private.
(JSC::ParserError::isValid):
To client of the interface cared about the type of the error,
the only information needed was: is there an error.
