[MC] Common symbols weren't being checked for redeclaration which allowed an assembly file to generate an assertion in setCommon(): !isCommon(). This change allows redeclaration as long as the size and alignment match exactly, otherwise report a fatal error. llvm-svn: 239227 2015-06-07 04:12:40 +08:00			`# RUN: not llvm-mc -filetype=obj -triple x86_64-pc-linux %s 2>&1 \| FileCheck %s`
