Revert 253497 and 253539 to try to fix clang-cmake-mips buildbot.

It caused link errors of the form:
InstrProfiling.c:(.text.__llvm_profile_instrument_target+0x1c0): undefined reference to `__sync_fetch_and_add_8'

We had a network outage at the time of the commit so the first build to show a
problem is http://lab.llvm.org:8011/builders/clang-cmake-mips/builds/10827
