 commit 5724ea01c943bbc78b6c8b6bfa01a5d026d42f5a

     More accurate cost attribution for stacks.  Fixes #7818.

     Previously, stacks were always attributed to CCCS_SYSTEM.  Now, we
     attribute them to the CCS when the stack was allocated.  If a stack
     grows, new stack chunks inherit the CCS of the old stack.
