[cp-patches] Small Throwable patch

[Archie Cobbs]

I'm planning to commit this patch. The reason for it is that the
logic of initCause() is unnecessary in the constructor, and represents
unnecessary overhead which we pay for every time a chained exception
is created. The effect is especially exacerbated when the constructor
invocation is inlined at every instantiation site, bloating code size.

Note that initCause() is not final, so a subclass could override it;
however the constructor does not specify that it calls initCause() to
initialize the cause so this doesn't change any specified behavior.
