[X86] Convert an instruction relaxation test to use objdump instead of readobj Patch by: david.l.kreitzer@intel.com git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@241270 91177308-0d34-0410-b5e6-96231b3b80d8

// RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu %s -o - | llvm-objdump -d - | FileCheck %s
Implement some relaxations for arithmetic instructions. The limitation on RIP relative relocations looks artificial, but this is a superset of what we were able to do before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117364 91177308-0d34-0410-b5e6-96231b3b80d8

// Test that we correctly relax these instructions into versions that use
// 16 or 32 bit immediate values.
