Make cumulative heap profile data optional.

Add the R option to control whether cumulative heap profile data
are maintained.  Add the T option to control the size of per thread
backtrace caches, primarily because when the R option is specified,
backtraces that no longer have allocations associated with them are
discarded as soon as no thread caches refer to them.
