[ObjectYAML] Support for DWARF debug_info section
This patch adds support for YAML<->DWARF for debug_info sections.
This re-lands r290147, reverted in 290148, re-landed in r290204 after fixing the issue that caused bots to fail (thank you UBSan!), and reverted again in r290209 due to failures on big endian systems.
After adding support for preserving endianness, this should be good now.
