The tool llvm-symbolize translates a code address to corresponding
function and finds information about location of that function in sources.
In some cases the address to function translation requires custom
procedure and is made separately so that only translation of function name
to source information is needed.

This change implements such translation in llvm-symbolize using command
SYMBOL, like in the example:

  llvm-symbolize --obj=abc.so "SYMBOL func_22"

The translation is supported for functions only and requires
availability of DWARF debug information.
