  -----------
  [ThinLTO] Disable "Always import constants" due to compile time issues

Summary:
Disable the always importing of constants introduced in D70404 by
default under a new internal option, since it is causing order of
magnitude compile time regressions during the thin link. Will continue
investigating why the regressions occur.
