Unless this is what Webkit uses as error message (we should generally match
those), it should say that it's only increment/decrement postfix and prefix
operators that must not be eval or arguments (i.e., when the operand must be an
LValue), and not, e.g., the "!" operator.

Webkit only says "parse error". Updated the errors to refer to incr/decr only. I
still have the bug open to eventually go through all the error messages and
reconcile them with jsc and mozilla.
