Invoke static/direct dispatch change.

There was a subtle race in static/direct dispatch via the code and methods
table. This patch removes the table in preparation of architectures like
x86 which will more aggressively sink loads.

Removes unused fields, code.. Brings back resolved methods table
short-cut and associated fast paths to use this (such as in Proxy). Adds
a resolution method that is used as the trampoline for static and direct
methods.

Add source file and line number to Throwable::Dump.

MethodHelper knowledge of runtime methods.
