perf tools: Add mem access sampling core support
This patch adds the sorting and histogram support
functions to enable profiling of memory accesses.
The following sorting orders are added:
- symbol_daddr: data address symbol (or raw address)
- dso_daddr: data address shared object
- locked: access uses locked transaction
- tlb : TLB access
- mem : memory level of the access (L1, L2, L3, RAM, ...)
- snoop: access snoop mode

[ committer note: changed to cope with fc5871ed, the move of methods to
machine.[ch], and the rename of dsrc to data_src, to match the change
made in the PERF_SAMPLE_DSRC in a previous patch. ]
