Here are sizes of Clang linked with ld, gold and LLD with or without
--gc-sections.

ld
56321983
56253215

gold
57765632
57696264

LLD
57765712
55296872

LLD produces the smallest executable as you can see, but that's so good
that that is odd. I don't have a good theory at this moment to describe the
difference.
