For now, this only builds the dylib, so using `-fsanitize=undefined`
with `-static-libsan` or `fsanitize-minimal-runtime` still won't
work -- but the common case does work.

Our support for building for baremetal was conditional on a default
off arg and would have failed to build if you had somehow arranged
to pass the correct --target flag; presumably nobody noticed because
nobody was turning it on. A better approach is to model baremetal
as a separate "OS" called "baremetal" and build it in the same way
as we cross-compile for other targets. That's what this patch does.
I only hooked up the arm64 target but others can be added.
Relanding after fixing Mac build breakage in D123244.

I've been using this triple in development for a while without issues,
it's passing check-llvm and check-clang.
(The above is the commit message, but the build is currently broken since
D114639, I intend to submit this once it's passing again and it's accepted in
review)

With these changes, check-asan passes on Linux and Windows.
There are a couple libraries we need to add support for, asan_static, asan_preinit, and the shared library version of asan proper.
Since we need to build the asan proper sources twice, once with -DASAN_DYNAMIC and once without, those sources are no longer in a source_set.
Much of the check-asan target is taken from the existing check-hwasan target.

crt_code seems to correspond to SANITIZER_COMMON_CFLAGS which contains -fno-builtin.

This was done for check-hwasan, but compiler-rt/test/hwasan/lit.cfg.py
already does that.
This makes check-asan (to be submitted) fail on Windows due to using
lld-link (as opposed to MSVC link.exe) in tests. That seems like a
problem that should be fixed, but that's orthogonal to this patch.
