I see now that `consumeError` is 'throwing away' errors in some sense.

This function, `getNMSectionTagAndName` is the rename of `getNMTypeChar`. `getNMTypeChar` calls `getSymbolNMTypeChar` for different kinds of object files.

Since I needed to do something special for ELF, I guarded my code for ELF, and mimicked the code in `getSymbolNMTypeChar`, the ELF version. `getSymbolNMTypeChar` for ELF (and also for COFF) has the same call to `getSection` and `consumeError`, without any comment indicating what they are doing.

If you have any suggestion as to what comment should go here, I will be happy to add it.
