A class that transforms the DWARF in a DWARFContext into GSYM information by populating the GsymCreator object that it is constructed with.
This class supports converting all DW_TAG_subprogram DIEs into gsym::FunctionInfo objects that includes line table information and inline function information. Creating a separate class to transform this data allows this class to be unit tested.

Create a DWARF transformer.
D | The DWARF to use when converting to GSYM. |
G | The GSYM creator to populate with the function information from the debug info. |

) |
Extract the DWARF from the supplied object file and convert it into the Gsym format in the GsymCreator object that is passed in.
Returns an error if something fatal is encountered.
NumThreads | The number of threads that the conversion process can use. |
OS | The stream to log warnings and non fatal issues to. If NULL then don't log. |
