We're removing GNU binutils in Android T, so lets redirect any last
remaining users to the LLVM equivalents sooner rather than later.
(This won't "just work" for ld versus lld, but it's likely that anyone
using TOOLS_PREFIX will need a few other tweaks anyway, and including
the "llvm-" prefix seems like it will cover most other cases.)

The behaviour is semantically identical, however,
the tool additionally sorts the symbols by address,
compresses frame unwind information more efficiently,
and improves random-accessibility for lazy decompression.
Overall, the changes balance and the output size is same,
however, libunwindstack can access the data much faster
while using less memory (due to the lazy decompression).
It will also enable further improvements in the future.

This allows setting per-module make variables earlier in the build,
particularly for prebuilt_build_tool users like LEX/M4/BISON. I moved
filegroup over because it's a simpler common interface, but it doesn't

When HWASAN is enabled, the runtime is conceptually part of Bionic (and
mutually depends on it), so it needs to be treated in the same way as the
Bionic libs.
Now there are only two copies of the runtime: the one in
/system/lib64/bootstrap (which won't be used by ordinary processes) and the
one in the runtime APEX.
This reduces the size of the HWASAN system image and fixes an issue where
multiple copies of the HWASAN runtime were being loaded into 64-bit binaries in
APEXes because the linker namespace for the binary is different from the one
for its dependent libraries outside of APEXes. HWASAN only supports loading
one copy of the runtime per process, so this was causing such binaries to
crash on startup.

When no-vendor-variant VNDK is enabled, the vendor variant of VNDK
libraries are not installed. Since not all VNDK libraries will be
ready for this, we keep a list of library names in cc/vndk.go to

installed regardless of whether no-vendor-variant VNDK is enabled.
Also add --remove-build-id option to the strip script to facilitate
the check of functional identity of the two variants.

When building with two OSes of the same class (Host, etc) enabled,

making `compile_multilib: "first"` select just one of the OSes.

Host class, but this would also applied if we wanted to generate rules

This is a new sanitizer similar to ASan, but with a few differences
from the build system perspective:
* Only runs on AArch64.
* Supports static binaries.
* Bionic itself will be built with HWASan.
* Does not have any "if a library is sanitized than the binary must
be, too" requirements unlike ASan. Even better, individual static
libraries can be freely sanitized or not. We propagate "nosanitize"
from binaries to static libraries anyway, because otherwise there
is no good way to disable hwasan on a binary as a whole.
Same a CFI, we export a list of sanitized static libraries to make.
In fact, we export separate lists for vendor and regular libraries,
because it is possible for one to be sanitized without the other
(i.e. there can be mylib.hwasan.vendor w/o mylib.hwasan or vice
versa).

Normally, when building with VNDK, platform modules are not allowed to
link against vendor libraries, because the ABI of the vendor libraries
are not guaranteed to be stable and may differ across multiple vendor
images.
However, the vendor public libraries are the exceptions. Vendor public
libraries are vendor libraries that are exposed to 3rd party apps and
listed in /vendor/etc/public.libraries.txt. Since they are intended to
be exposed to public, their ABI stability is guaranteed (by definition,
though it is up to the vendor to actually guarantee it).
This change provides a way to make a vendor lib as public by defining a
module of type 'vendor_public_library' with a map file that enumerates
public symbols that are publicized:
cc_library {
name: "libvendor",
proprietary: true,
...
}
vendor_public_library {
name: "libvendor",
symbol_file: "libvendor.map.txt",
}
This defines a stub library module named libvendor.vendorpublic from the
map file. `shared_libs: ["libvendor"]` is redirected to the stub library
when it is from the outside of the vendor partition.
