Arch property struct types are created at runtime. Go has a limit
of 2**16 bytes for the name of a type, and the type of a struct
created at runtime is a string containing all the names and types
of its fields. To avoid going over the limit, split the runtime
created structs into multiple shards.
Also undo MoreBaseLinkerProperties now that it is no longer
required.

llvm-ar takes a --plugin argument but it is ignored for compatibility,
so passing it has no effect.

Some tools (eg ccls) require that the compiler in argv[0] of the
compdb be an actual compiler binary. Until now we had simply filled
that slot with /bin/false. This change fills it with the current
default clang binary instead.

Export static libraries through LOCAL_STATIC_LIBRARIES and
LOCAL_WHOLE_STATIC_LIBRARIES. This enables dependency-based NOTICE file
generation. Also, add a notice property in the libwinpthread module.

When building against libFoo#ver, __LIBFOO_API__ macro is set to ver so
that headers from libFoo can be conditionally compiled (e.g., hide APIs
that are not available for the version, etc.)

This commit replaces versioner host binary (built just-in-time) with
a prebuilt binary under `prebuilts/clang-tools/${OS}/bin/versioner`.
This is a part of the effort to switch to clang-r339409b.

A cc_library or cc_library_shared can be configured to have stubs
variants of the lib.
cc_library_shared {
name: "libfoo",
srcs: ["foo.cpp"],
stubs: {
symbol_file: "foo.map.txt",
versions: ["1", "2", "3"],
},
}
then, stubs variants of libfoo for version 1, 2, and 3 are created
from foo.map.txt. Each version has the symbols from the map file where
each symbol is annotated with the version that the symbol was introduced
via the 'introduced=<ver>' syntax. The versions don't need to be in sync
with the platform versions (e.g., P for 28). The versions are local to
the library.
For another library or executable to use the versioned stubs lib, use
the new 'name#ver' syntax to specify the version:
cc_binary {
name: "test",
....
shared_libs: ["libFoo#2"],
}
Internally, a new mutator 'version' is applied to all cc.Module objects.
By default, a variant named 'impl' is created for the non-stub version.
If the versions property is set, additional variations are created per a
version with the mutable property BuildStubs set as true, which lets the
compiler and the linker to build a stubs lib from the symbol file
instead from the source files.
This feature will be used to enforce stable interfaces among APEXs. When
a lib foo in an APEX is depending on a lib bar in another APEX, then bar
should have stable interface (in C lang) and foo should be depending on
one of the stubs libs of bar. Only libraries in the same APEX as foo can
link against non-stub version of it.

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.

This is achieved via the compiler flag -ffixed-x18 for non-LTO builds
and the linker flag -plugin-opt -mattr=+reserve-x18 for LTO builds.
This change should be reverted once we upgrade past LLVM r340889
which does this by default on Android.
