Summary:
We are using symbols to represent label and csect interchangeably before, and that could be a problem.
There are cases we would need to add storage mapping class to the symbol if that symbol is actually the name of a csect, but it's hard for us to figure out whether that symbol is a label or csect.
This patch intend to do the following:
1. Construct a QualName (A name include the storage mapping class)
MCSymbolXCOFF for every MCSectionXCOFF.
2. Keep a pointer to that QualName inside of MCSectionXCOFF.
3. Use that QualName whenever we need a symbol refers to that
MCSectionXCOFF.
4. Adapt the snowball effect from the above changes in
XCOFFObjectWriter.cpp.
