gold, readelf: add experimental support for SHT_RELR sections.
This change adds experimental support for SHT_RELR sections, proposed
here: https://groups.google.com/forum/#!topic/generic-abi/bX460iggiKg
SHT_RELR sections are supported for arm, aarch64, and x86_64 targets.
To enable them, pass '--experimental-use-relr' flag to gold.
Definitions for the new ELF section type and dynamic array tags, as well
as the encoding used in the new section are all under discussion and are
subject to change. Use with caution!
Bug: None
Test: 'gold --experimental-use-relr' creates PIE binaries with
'.relr.dyn' sections to store relative relocations.
