Gentoo supports combining clang toolchain with GNU binutils, and many

this results in a lot of warnings. Disable it by default and let users
enable it explicitly if they want it; with the intent of reevaluating
when the underlying feature becomes standarized.

The problem that required a revert was fixed in r337338.
Also added a missing "REQUIRES: x86-registered-target" to one of
the tests.

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.
