For reasons explained in the commit contents, in order to build the
native gnat package for x86_64-darwin, the native gnatboot package for
x86_64-darwin must have access to both the Clang integrated assembler
and the cctools GNU assembler for that platform. This commit creates a
package with both of those assemblers that x86_64-darwin gnatboot can
then be wrapped with.

- Use the 11.0 SDK instead of the 10.12 one on x86_64-darwin;
- Use `NIX_CFLAGS_COMPILE` and `NIX_LDFLAGS` to pass flags to the
compiler instead of patching the Xcode project files; and
- Use xcbuild to build the project.
- Introduce `preLibcCrossHeaders` to bootstrap libgcc and compiler-rt
the same way.
- Organize LLVM bintools as `bintools{-unwrapped,,NoLibc}` for
consistency with GNU Binutils and Apple's cctools.
- Do Android changes for all `llvmPackages` for consistency.
- Improve the way the default GCC and LLVM versions are selected.
I am taking the non-invasive parts of #110914 to hopefully help out with #111988.
In particular:
- Use `lib.makeScopeWithSplicing` to make the `darwin` package set have
a proper `callPackage`.
- Adjust Darwin `stdenv`'s overlays keeping things from the previous
stage to not stick around too much.
- Expose `binutilsNoLibc` / `darwin.binutilsNoLibc` to hopefully get us
closer to a unified LLVM and GCC bootstrap.
Without this change `as` on `aarch64-darwin` is defunct:

```
Apple defaults to Clang in all cases from what I see, but nixpkgs prefers `cctools`: #51881.
The only remaining use-case for cf-private are symbols that are not
available in the opensource build. This generally solved the problem
because of it's setup-hook.
CoreFoundation is included by the stdenv, moving the decision of what
version should be used there makes it possible to override it entirely
rather then prepending flags like cf-private does which can be
unreliable.
Lots of stuff has gotten moved around. Many security libraries have been merged
into the Security monorepo. I’ve cleared them out for now, we will
need to modify Security to build them!
This also moves some things around to more clearly separate
bootstrapping the stdenv from everything else. We want the “normal”
mode to be the non-bootstrapped version. When you ask for “Security”,
you want the actual built software, not a crippled one.
- Add TARGET_OS_OSX to darwin.libSystem. Looks like something
introduced in 10.12. TARGET_OS_MAC is only set when building for
desktop (iOS will have TARGET_OS_MAC set)
- Bump darwin.dtrace
- Bump darwin.libpthread
- Remove SmartCardServices, libsecurity*, etc.
- Install some more headers for darling.
We were previously using a dummy wrapper for dsymutil. This meant that
debug symbols were not getting generated when dsymutil was otherwise
available. This should fix that issue & provide a real dsymutil from
llvm.
Fixes#52148.

This also updates the bootstrap tool builder to LLVM 5, but not the ones
we actually use for bootstrap. I'll make that change in a subsequent commit
so as to provide traceable provenance of the bootstrap tools.
This is the newest sdk. I have skipped 9.3 for now but someone can
certainly add it if they need it for some reason.
Also I added a generic "xcode" that will always point to the newest
xcode that is available in Nixpkgs.
