While debugging module support using -Wsystem-headers, we discovered that if
-Werror, and -Wundef or -Wmacro-redefined are specified, they can cause errors
to be generated in these builtin headers.

e5ccd66801 and
5029dce492 added deprecation warnings to
the <stdbool.h> and <stdnoreturn.h> headers, respectively, because the
headers are deprecated in C2x.
However, there are system headers that include these headers
unconditionally, and #warning diagnostics within system headers are
shown to users instead of suppressed, which means these deprecation
warnings are being triggered in circumstances that users have no
control over except to disable all the warnings through the
_CLANG_DISABLE_CRT_DEPRECATION_WARNINGS macro or other means.
This removes the problematic #warning uses until we find a more
palatable solution.
Summary:
These all had somewhat custom file headers with different text from the
ones I searched for previously, and so I missed them. Thanks to Hal and
Kristina and others who prompted me to fix this, and sorry it took so
long.

lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
