Like shared libraries, the bootstrap subdirectory is appended to the
install path only when the module is in an APEX. Currently, this change
doesn't make any difference because only the Bionic binary (linker) is
satisfying the existing condition InstallToBootstrap() and it already
satisfies DirectlyInAnyApex.
However, this change makes a diference when we build the binary for the
host targets. Then without this change, it is installed to
out/soong/host/<OS>-<arch>/bin/bootstrap. This doesn't make sense
because we don't use APEXes for the host targets. With this change,
the binary is correctly installed to out/soong/host/<OS>-<arch>/bin
because DirectlyInAnyApex returns false for hosts.

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.

(cherry picked from commit 4d8d8fec4a)
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.

libdl.a has a no-op dlopen, which breaks static libraries that need a real
dlopen. Instead of automatically linking libdl.a into static executables,
make it optional.
Until recently, the libunwind_llvm.a unwinder, used on arm32, needed the
no-op dladdr, but it's now built using -D_LIBUNWIND_USE_DLADDR=0.
The HWASan run-time uses dlsym and dladdr, so add a libdl dependency for
HWASan-built static binaries. We could also remove the dependency from
libclang_rt.hwasan_static-*.a, but this is also easy to do.

Ensure that it ends up in the bionic/ subdir in the Runtime APEX and is
symlinked from /system/lib(64). That makes it available in the default
(platform) linker namespace and no longer requires it to be accessible
through the runtime namespace. All this makes it consistent with how the
other Bionic libs are handled, and avoids the need for various special
cases in ld.config.txt files (to be cleaned up later).
With this there might no longer be a need for a linker namespace for the
Runtime APEX, and we could consider removing the kludge with the
/apex/com.android.runtime/${LIB}/bionic subdirectories and the special case
in getCopyManifestForNativeLibrary in apex.go. However, keeping it calls out
the special treatment of those libraries, and allows a namespace to be added
again if necessary.

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.

The following flags that the binutils linkers support are not
available in lld for Windows:
-soname
--no-undefined
-rpath
Windows also uses "import libraries", which are stub libraries used only
for linking. The binutils linkers accepted a DLL and treated them as an
import library. But lld issues the following error:
lld-link: error: ...DLL: bad file type. Did you specify a DLL instead
of an import library?
To resolve this, pass '-out-implib=libFoo.lib' to lld when linking
libFoo.dll to get lld to generate an import library. Add libFoo.lib as
an implicit output to the 'ld' build rule.
Rewrite the shared libraries when building a library/binary to use the
import library instead of the DLL. As a side-effect, this also uses the
newly-created AdbWinApi.lib that's alongside

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).

This change fixes following problem:
1) a native lib having stubs is defined.
2) the lib is included in an APEX.
3) a static binary is linking the lib from outside of the APEX.
4) then, the dependency from the binary to the lib is vanishing.
This is happening because cc.depsToPaths() mistakely does not
distinguish static lib deps from shared lib deps. For shared lib deps,
it creates two dependencies (one for stubs variant and the other for
non-stubs variant) and choose the stubs variant when the lib and the
current module is not in the same APEX (i.e. dependency to the non-stubs
variant is discarded). However, since we don't have stubs variant for
static library, it ends up having no dependency to the library if the
link is static.
Fixing the issue by skipping the variant selection routine when the link
is static.
