[XCOFF][AIX] Differentiate usage of label symbol and csect symbol
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.
