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.
