This is the 7th version of the patch set to extend "counted_by" attribute to pointer fields of structures.
The C FE parts (patch #1 and #3) of the 5th version have been approved by Joseph already (with a minor typo fix, which is included in this new version); The middle end part (patch #2) of the 6th version was reviewed by Sid and Richard, Sid raised several format issues in testing cases, and Richard raised one issue in tree-object-size.cc. In this 7th version, I fixed all the format issues in testing cases and also the one issue in tree-object-size.cc raised by Richard. The whole patch set has been bootstrapped and regression tested on both aarch64 and x86. Okay for trunk? Thanks a lot. Qing
