commit 745bdd88f9e4f9c85d46e84c58d6799bf71725b7
Author: Edward Z. Yang <ezyang at cs.stanford.edu>

    Unconditionally handle TH known key names.
    
    Previously, we didn't add Template Haskell key names to the list
    of known uniques when building a stage 1 compiler.  But with
    f16ddcee0c64a92ab911a7841a8cf64e3ac671fd we may refer to TH
    names even in stage 1, and this was causing uniques to not
    be setup properly.

    Test Plan: validate and run stage1 test suite
