This adds a toolchain definition for LinuxBionic that only supports
Clang/64-bit. It pulls pieces from the x86_linux_host and x86_64_device
configs, and uses the android clang triple, with some manual overrides.
To enable building this, set your soong.config file to:
{"Host_bionic": true}

This is configured the same as make -- a global NATIVE_COVERAGE=true
flag to allow native coverage, then COVERAGE_PATHS=path1,path2,... to
turn it on for certain paths.
There are .gcnodir files exported to Make and saved in $OUT/coverage/...
files which are `ar` archives containing all of the compiler-produced
.gcno files for a particular executable / shared library.
Unlike the Make implementation, this only passes links the helper
library (automatically through --coverage) when one of the object files
or static libraries being used actually has coverage enabled.
Host support is currently disabled, since we set -nodefaultlibs, which
prevents libclang_rt.profile-*.a from being picked up automatically.
Bug: 32749731
Test: NATIVE_COVERAGE=true COVERAGE_PATHS=system/core/libcutils m -j libbacktrace libutils tombstoned
$OUT/coverage/system/lib*/libcutils.gcnodir looks correct (self)
$OUT/coverage/system/lib*/libbacktrace.gcnodir looks correct (static)
$OUT/coverage/system/lib*/libutils.gcnodir doesn't exist (shared)
$OUT/coverage/system/bin/tombstoned.gcnodir looks correct (executable)
Test: NATIVE_COVERAGE=true COVERAGE_PATHS=external/libcxxabi m -j libc++
Confirm that $OUT/coverage/system/lib*/libc++.gcnodir looks correct (whole_static_libs)

-pie triggers a bug in glibc's linker when used with goma
(https://sourceware.org/bugzilla/show_bug.cgi?id=16381). Allow
the clang build to disable -pie for host modules through the
DISABLE_HOST_PIE environment variable so it can produce a toolchain
that works with goma.

The linker uses libc++_static but needs to avoid the libc.a
dependency. It does this by setting `stl: "none"` and manually
linking libc++. This behavior matches make.
A better approach would probably be to generalize system_shared_libs
to system_libs and apply those to static executables the same way we
do for dynamic ones, but that's a patch for another day.

Move symlink installation into the binaryDecorator so that it can
access the suffix and extension when installing symlinks. Also
consolidates the symlink and symlink_preferred_arch handling.

Export a list of libraries in the VNDK, which is currently empty.
Take in Make's global BOARD_VNDK_VERSION, and use that as the SDK
version for modules that specify use_vndk: true.
Modules that use the vndk have some configuration as if they were
building against the NDK (the absence of globally defined headers), but
in other cases look like platform modules (using the platform libc++,
for now).
This change does not attempt to enforce any linking constraints, that
will come in a later patch.
Test: out/soong/build.ninja doesn't change

Move some cc ctx.Host() / ctx.Device() checks over to using

We need to fall back to the old CRT objects since we aren't generating

For every file which we can run clang-tidy (C/C++ clang-built), we add a
new build node that depends on the object file (since clang-tidy does
not export a depfile), and is depended on by the link step. This is
better than how we're doing it in make, since calling tidy can be turned
on or off without needing to rebuild the object files.
This does not attempt to port WITH_TIDY_ONLY from Make, since the way
that it works is broken (due to the lack of a depfile).

Add a symlink_preferred_arch property to binaries to allow compiling the
