runtime: fix mem profile when both large and small objects are allocated at the same stack
Currently small and large (size>rate) objects are merged into a single entry.
But rate adjusting is required only for small objects.
As a result pprof either incorrectly adjusts large objects
or does not adjust small objects.
With this change objects of different sizes are stored in different buckets.

Hello golang-dev@googlegroups.com (cc: golang-codereviews@googlegroups.com),

I'd like you to review this change to
https://dvyukov%40google.com@code.google.com/p/go/

Replacing golang-dev with golang-codereviews.

To the author of this CL: 

If you are using 'hg mail -r golang-dev' to mail the CL, use simply 'hg mail'
instead.

If you did not name golang-dev explicitly and it was still added to the CL,
it means your working copy of the repo has a stale codereview.cfg
(or lib/codereview/codereview.cfg).
Please run 'hg sync' to update your client to the most recent codereview.cfg.
If the most recent codereview.cfg has defaultcc set to golang-dev instead of
golang-codereviews, please send a CL correcting it.

Thanks very much.

This CL appears to have broken the linux-arm-cheney-panda builder.
