Fangrui Song 5387c2cd17 [llvm-objdump] Print newlines before and after "Disassembly of section ...:" 
This improves readability and the behavior is consistent with GNU objdump.

The new test test/tools/llvm-objdump/X86/disassemble-section-name.s
checks we print newlines before and after "Disassembly of section ...:"

Quentin Colombet 25b43f3624 [X86] Add relaxtion logic for SBB instructions. 
Prior to this patch, we would wrongly stick to the variant with imm8 encoding
even when the relocation could not fit that size.

Michael Kuperstein 5f05153fbb [X86] Fix incorrect/inefficient pushw encodings for x86-64 targets 
Correctly support assembling "pushw $imm8" on x86-64 targets. 
Also some cleanup of the PUSH instructions (PUSH64i16 and PUSHi16 actually
represent the same instruction)

This fixes PR23996

Rafael Espindola e8ae98817a 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.
