object text section header and symbol entry for rogram code.
SUMMARY:
Original form of this patch is provided by Stefan Pintillie.
1. The patch try to output program code section header , symbol entry for
program code (PR) and Instruction into the raw text section.
2. The patch include how to alignment and layout the CSection in the text
section.
3. The patch also reorganize the code , put some codes into a function.

Additional: We can not add raw data of text section test in the patch, If want
to output raw text section data,it need a function description patch first.

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.
