Enable assembly output of local commons for AIX Summary: This patch enable assembly output of local commons for AIX using .lcomm directives. Adds a EmitXCOFFLocalCommonSymbol to MCStreamer so we can emit the AIX version of .lcomm assembly directives which include a csect name. Handle the case of BSS locals in PPCAIXAsmPrinter by using EmitXCOFFLocalCommonSymbol. Adds a test for generating .lcomm on AIX Targets.

[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. Reviewers: xingxue, DiggerLin, sfertile, daltenty, hubert.reinterpretcast Reviewed By: DiggerLin, daltenty Subscribers: wuzish, nemanjai, mgorny, hiraditya, kbarton, jsji, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D69633
