Summary: pp tools give different results

Initial Comment:
could be also labeled as zero symbols size.

cumulating samples from oprofpp give different results
from op_time. The problem occur because op_bfd
give zero size for symbols when two symbols exist
at the same vma. We calculate symbol size by the
difference between next symbol vma and the symbol
vma. Unhopefully we removed duplicated symbol at the
same vma after calculating the size so size of those
symbols was always zero.

op_time -l, oprofpp, op_to_source are affected by
this bug. This typically happen in shared lib wich
define alias name for some symbol e.g. libpthread
__pthread_mutex_lock and pthread_mutex_lock.
libpthread is massively affected by this bug.
glibc results was also affected by this problem.

I'll commit a fix after teting it


regards,
Phil
