which was reverted in r337336.

The problem that required a revert was fixed in r337338.

Also added a missing "REQUIRES: x86-registered-target" to one of
the tests.

Peter Collingbourne 35c6996b68 Revert r337333, "Teach Clang to emit address-significance tables."
Causing multiple failures on sanitizer bots due to TLS symbol errors,
e.g.

/usr/bin/ld: __msan_origin_tls: TLS definition in /home/buildbots/ppc64be-clang-test/clang-ppc64be/stage1/lib/clang/7.0.0/lib/linux/libclang_rt.msan-powerpc64.a(msan.cc.o) section .tbss.__msan_origin_tls mismatches non-TLS reference in /tmp/lit_tmp_0a71tA/mallinfo-3ca75e.o

Peter Collingbourne 27242c0402 Teach Clang to emit address-significance tables.
By default, we emit an address-significance table on all ELF
targets when the integrated assembler is enabled. The emission of an
address-significance table can be controlled with the -faddrsig and
-fno-addrsig flags.
