Anon records usually do not have the 'execname' entry. However if they are on
the heap, the execname shows up as '[heap]'. The fix considers any executable
entries in the map that do not have a name or are on the heap as anon records
and sets the name to '//anon'.
This fixes JIT profiling for records on the heap.
