We used to enable unique names only when a profile is available.
But A profile generated for a binary without unique names doesn't
work well when building a binary with unique names. To avoid a
chicken-and-egg problem, this CL enables the flag when afdo=true,
whether a profile exists or not.

Previously we were treating it as a shared library only, but
cc_test_library produces both a static and shared library.

in bp2build. The context here is that `-fvisibility=default` should
only be added for CFI if `-fvisibility=hidden` is not already
specified. This will be achieved using toolchain features. Note
that Soong itself never adds `-fvisibility=hidden`. This is only
ever added in the `cflags` property of a bp file.

Environment variables HWASAN_INCLUDE_PATHS and
PRODUCT_HWASAN_INCLUDE_PATHS can be used to enable HWASan for multiple
modules, by just adding the module directory to the env variable.
Bug: b/271948407
Test: Set specific module directory to above env variable and check the
assembly codes of output elf files after building, finding hwasan
related symbols inside.

ld -r reorders symbols and invalidates the .llvm_addrsig section, which
then causes warnings if the resulting object is used with ld --icf=safe.
The warning is especially common when building with musl, as the
clang_rt.crt* objects have .llvm_addrsig sections, are linked into
libc_musl_crt* using ld -r, and are then linked into every other binary
and shared library with --icf=safe.
Strip the .llvm_addrsig section after ld -r to prevent the warnings.

The public stubs of libclang_rt.* originate from the same module. When
generating the Androidmk entries for these stubs, we need to add a
suffix to differentiate between the two stub variants.
This is likely an issue specific to libclang_rt.*. The public stubs of
other libraries like libc, liblog, ... come from a separate module
ndk_library which adds an .ndk suffix

We're switching from x18 to gp, in stages. This change frees up x18
again now bionic and ART have switched to gp. There's no need for a
corresponding "reserve gp" change because gp is automatically reserved.
That's what makes it the perfect choice for shadow call stack (at
least until we get Zsslpcfi and an actual hardware shadow stack pointer
special-purpose register).

without breaking anything, so let's disable shadow call stack while we

libc_hwasan is a new library in the runtime apex that lives in
bionic/hwasan/libc.so and is symlinked to /system/lib64/hwasan/libc.so.
This is chosen by the linker if an app or binary requires HWASan
support.

The actual NDK distribution will overwrite these (they're branded with
the platform's version information, which isn't what the NDK wants to
brand apps with), but including them here makes it easier to iterate
on the platform sysroot in situations that don't require a strictly
correct NDK sysroot.

Introducing fdo_profile module type to reimplement the afdo support in cc moduels. This change allows the feature to be compatible with Bazel migration.
How it works:
PreDepsMutators:
* BeginMutator: If non-static cc modules sets afdo prop, search and add corresponding fdo_profile module as a dep with fdoProfileTag
* fdoProfileMutator:
* If in fdo_profile module, set FdoProfileProvider with full path to profile
* If in cc module, read FdoProfileProvider from dep with fdoProfileTag and set FdoProfileInfo.Path to FdoProfilePath field
PostDepsMutators:
* afdoDepsMutator: If a module has FdoProfilePath set, walk to its static deps and set itself to the deps' AfdoRdeps
* afdoMutator: If a static dep has AfdoRDeps set, create afdo variant.
