Add back commits r219835 and a fixed version of r219829. The only difference from r219829 is using getOrCreateSectionSymbol(*ELFSec) instead of GetOrCreateSymbol(ELFSec->getSectionName()) in ELFObjectWriter which causes us to use the correct section symbol even if we have multiple sections with the same name. Original messages: r219829: Correctly handle references to section symbols. When processing assembly like .long .text we were creating a new undefined symbol .text. GAS on the other hand would handle that as a reference to the .text section. This patch implements that by creating the section symbols earlier so that they are visible during asm parsing. The patch also updates llvm-readobj to print the symbol number in the relocation dump so that the test can differentiate between two sections with the same name. r219835: Allow forward references to section symbols. llvm-svn: 220021 2014-10-17 09:48:58 +08:00			`// RUN: not llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu %s -o %t.o 2>&1 \| FileCheck %s`
