Liz Kammer a060c4521e Handle product_variable asflag for cc_object.
cc_object crtbrand sets product_variable.platform_sdk_version.asflag
and will not compile correctly within mixed builds without it.

Only handles product_variables that expand product variables.

Jingwen Chen 12b4c2706d bp2build: add allowlist for package-level conversions.
This CL adds the support for specifying lists of directories in
build/soong/android/bazel.go, which are then written into
out/soong/bp2build/MANIFEST. Using this configuration,
modules/directories can either default to bp2build_available: true or
false, while still retaining the ability to opt-in or out at the module level.

It also ensures that ConvertWithBp2Build returns true iff the module
type has a registered bp2build converter.

Jingwen Chen 5d8644990b bp2build: add configurable attribute (select) support.
This CL adds a basic framework to support configurable string_list
attributes, selecting on the Arch variant (x86, x86_64, arm, arm64).

It offers fine-grained controls to map individual configurable
properties (arch_variant) to configurable Bazel attributes, starting
with the string_list type for the copts property for cc_object.

This design is primarily motivated to have minimal boilerplate in
bp2build mutators, allowing anyone to opt-in configurable attributes,
and modify intermediate states before passing them on into the
CreateBazelTargetModule instantiator.

Jingwen Chen 8c1b97e01b bp2build: cc_object converter.
This CL introduces a basic bp2build converter for cc_object modules.
cc_objects maps cleanly to cc_library targets, but with -fnoaddrsig.

This CL also demonstrates generating include deps within a macro to
allow the cc_object compilation to depend on a relative-include header
within an include dir.

e.g. if "foo.cc" includes "android/log.h" and the latter is located at
"include/android/log.h", the autogenerated header deps would export
"android/log.h" correctly to the foo.cc upstream target.

Dan Albert 92fe740677 Stop using prebuilt NDK CRT objects.
We don't need the prebuilt versions. The NDK CRT objects are (now)
built from the platform sources and the only difference is that the
NDK CRT objects also include an ELF note that identifies the NDK
version, which isn't helpful for anything built by the platform.

Add a `crt` property to cc_object that allows CRT objects to identify
themselves. CRT objects, unlike other modules, will have a variant
built per-API level they support, rather than just an SDK variant and
a platform variant. This is needed because new CRT objects will rely
on APIs not available in old libcs and old CRT objects will not
support all the features of a modern one.

Colin Cross 4af21ed26f Split local and global cflags
Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags

This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags.  A better order
would be:
global cflags
global conlyflags
global cppflags
local cflags
local conlyflags
local cppflags
local include dirs
global include dirs

We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them.  This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

Peter Collingbourne 1c648b8936 Allow sanitize attribute on cc_objects and propagate sanitize attributes into them.
Without this change, we can end up failing to sanitize parts of libraries
that are compiled as cc_objects, such as bcm_object.o in boringssl. This
is normally harmless (except that the sanitizer would fail to detect bugs
in unsanitized code), however boringssl in particular needs to be compiled
with HWASAN enabled in all translation units in order to avoid link errors
with newer toolchains that support HWASAN global instrumentation.

Pirama Arumuga Nainar 65c95ff1fb Include libprofile-extras to all coverage variants
Bug: http://b/128524141

Include libprofile-extras (defined in system/extras/toolchain-extras) to
all modules that need a coverage variant.  Also add
'-uinit_profile_extras' when linking with coverage.  This causes the
setup code in libprofile-extras to be linked into binaries/libraries
with coverage enabled.

We add the static library to the non-coverage variants as well but is a
no-op for them (since the '-u...' flag is not added for them).

Adding this dependency creates several circular dependencies since
coverage variants were being created for other module types that never
had any compilation or linking done during the build.  This change stops
creating coverage variants for toolchain_library, cc_prebuilt_library_*,
cc_library_headers module types (by adding a function to the linker
interface to specify whether native coverage is enabled).

Support for safe ICF was added to LLD in LLVM r337429. This reduces
the size of sailfish system.img by 7.6MB.

The address-significance tables created by Clang to support LLD's
implementation of safe ICF are incompatible with ld -r. Therefore we
need to pass -fno-addrsig to the compiler to prevent it from creating
an address-significance table when building a cc_object.
