I don't find these specific log statements particularly high value, as they
appear more just like simple function tracing calls (i.e. they log low level
implementation details, not high level program flow) so I'm removing them from
the low level DWARF parsing libraries.
I'm prepared to be convinced that we actually should do something other than
outright delete them, but I did look at each one specifically as well as the
surrounding context before deciding that they were probably ok to delete.
My reasoning for deleting these is that they are all on the success codepath
and have a very limited number of call-sites (in most cases actually just 1),
so in most cases a previous log statement would necessarily be followed by the
deleted log statement, so therefore it doesn't actually add much (if any)
diagnostic value.
