PPC: Array() in optimized code can create with wrong ElementsKind in corner cases.

PPC: Array() in optimized code can create with wrong ElementsKind in corner cases.

Port 13459c1ae3caa4cc546c522177bac5450a3252bf

Original commit message:
Calling new Array(JSObject::kInitialMaxFastElementArray) in optimized code
makes a stub call that bails out due to the length. Currently, the bailout
code a) doesn't have the allocation site, and b) wouldn't use it if it did
because the length is perceived to be too high.

This CL passes the allocation site to the stub call (rather than undefined),
and alters the bailout code to utilize the feedback.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
