a3465838bc Contribution of PowerPC port (continuation of 422063005) - currency 
Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. This patch updates the ppc directories
to make them current with changes in common code, removes the
optimization to use the ool constant pool, and excludes tests that
don't pass under the ppc simulator given a 240s timeout.

Subsequent patches will cover:
   - remaining optimizations for PPC
   - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX)
   - incremental updates required to ppc directories due to platform specific changes made
    in google repos while we complete the above steps.

1eddcf5b71 [strong] Declaration-after-use errors. 
We cannot yet detect use-before-declaration in general, because for that we'd
need to analyze the context when compiling. But we can detect an error case
where we first see a use, then a declaration.

For this, I also added end position tracking (needed for error messages) to
VariableProxy.

Note: the position naming is completely inconsistent: start_position &
end_position, position & end_position, pos & end_pos, beg_pos & end_pos, to name
a few. This doesn't fix all of it, but tries to unify towards start_position &
end_position whenever possible w/ minimal changes.

36e72aedf0 ES6 collections: Fix order of constructor logic 
The adder should be gotten before the iterator.

Motivation: Once this is done we should be able to use a for-of loop
instead which leads to cleaner code and correct behavior once the
for-of loop correctly supports abrupt completion.
