c21ddbdcce Recognize new clang and clang-tidy warnings.
* Count new clang-tidy warnings:
    google-runtime-references
    google-runtime-operator
* Count new clang warnings:
    -Wconst-conversion similar to -Wliteral-conversion
    -Wundefined-var-template
* Modified static analyzer warning message about
    "Null passed to a callee that requires a non-null ..."
* Disable google-runtime-references by default and
  disable misc-macro-parentheses in vendor projects;
  too many old C/C++ code have this warning.

056609ccfe Remove unnecessary variables
These are all either recently unused due to the removal of CFLAGS/etc,
or have been exported by Soong and are no longer necessary.

02268f01df Move to a single clang unknown flags list
Soong is using a single list of unknown clang flags for all
architectures, instead of the per-architecture list here. Collapse this
down to a single list as well so that it can be verified against the
Soong list, and eventually replaced by the Soong version.

174feb906f Remove (C|CPP|CONLY|LD)FLAGS checked by Soong
At the beginning of every build, Soong has exported its version of these
variables, and has been ensuring that when sorted, the result is the
same. So these variables all have the same flags of the Soong ones, but
may be in different orders. We don't believe any of the remaining order
differences matter. As we remove the Make definitions, the exported
Soong variables will take over.

This only removes lines that change one of these variables:

  [2ND_][CLANG_]HOST_CROSS_GLOBAL_CFLAGS
  [2ND_][CLANG_]HOST_CROSS_GLOBAL_CONLYFLAGS
  [2ND_][CLANG_]HOST_CROSS_GLOBAL_CPPFLAGS
  [2ND_][CLANG_]HOST_CROSS_GLOBAL_LDFLAGS
  [2ND_][CLANG_]HOST_GLOBAL_CFLAGS
  [2ND_][CLANG_]HOST_GLOBAL_CONLYFLAGS
  [2ND_][CLANG_]HOST_GLOBAL_CPPFLAGS
  [2ND_][CLANG_]HOST_GLOBAL_LDFLAGS
  [2ND_][CLANG_]TARGET_GLOBAL_CFLAGS
  [2ND_][CLANG_]TARGET_GLOBAL_CONLYFLAGS
  [2ND_][CLANG_]TARGET_GLOBAL_CPPFLAGS
  [2ND_][CLANG_]TARGET_GLOBAL_LDFLAGS

Many other variables are unnecessary now too, but those will be removed
in another change. For those we can ensure the build.ninja file does not
change, but we expect it to change here due to the ordering differences.

4863dafcb1 Remove make variables exported from Soong
These have all been strictly checked by Soong, so the values currently
match. Just remove them so that the make variables exported by Soong
will take over.

This also removes some of the GCC reconfiguration, since we haven't
implemented that in Soong. If it becomes useful in the future, we'll
implement it there.

Some things like TARGET_TOOCHAIN_ROOT can nearly be removed, but are
used before the Soong-exported make_vars.mk is loaded. In that case,
added to the clang cflags, so it can be removed once the cflags are
removed.

Others, like LLVM_PREBUILTS_VERSION are loaded even earlier -- in
envsetup.sh before we've even configured Soong. So for now, keep the
Make definition, and continue ensuring it's the same as the Soong
version.

This reverts commit 3dfd20aea4 - the clang
version we are using has the mentioned permanent fix. The new build
system (Soong) uses a single list of unknown clang flags for all
architectures, so workarounds like this no longer work.

5ff9c81b6c Avoid accidentally using the host's native 'as' command.
When invoking clang for the host to assemble .S files, the -B flag
would not be provided, which allowed the host prebuilt clang to
use an 'as' from the native environment. Most of the time this
"just works", but some newer 'as' versions cause problems with
the older prebuilt toolchain, for example by generating
unsupported relocation types.

To avoid this problem, simply use the -B flag to tell clang to
invoke the assembler from the correct prebuilt gcc prefix.

9ecbf83259 Add 64-bit windows cross-compiles
This is mostly the same as the existing 2ND_HOST / HOST_CROSS support.

The interesting thing I did here was make x86 the 'first' architecture,
and x86_64 the second. This way LOCAL_MULTILIB := first defaults to
32-bit windows modules.

  windows-x86/bin   <- defaults to 32-bit executables
  windows-x86/lib   <- 32-bit libraries, like before
  windows-x86/lib64 <- 64-bit libraries
  windows-x86/obj   <- 32-bit intermediates
  windows-x86/obj64 <- 64-bit intermediates

Then modules are registered with the names:

  host_cross_liblog    <- 32-bit, like before
  host_cross_liblog_64 <- 64-bit

This change adds new variables for RS_LLVM_* tools, which correspond
to the version of LLVM checked in currently to external/, instead of
mapping to the latest host prebuilts. This will help prevent version
differences for newer IR generated by the updated host prebuilts, which
then might not be readable with the on-device LLVM bits we build from
external/.

505e4ec646 Be smarter about stack-protector on the host.
Some projects are still built with our host GCC 4.8, which doesn't
support -fstack-protector-strong. The combo .mk files are used by
GCC and clang, so it's not safe to turn on -fstack-protector-strong
there. Instead, do it in the clang-specific .mk for now.

We can clean this up when elfutils (the last code built for the host
with GCC that I'm aware of) is built by clang. We'll be able to
remove the host GCC prebuilts too!

6a66a887ba Stop encoding absolute paths in symbols
GCC & Clang encode the current working directory into the symbol files.
Even if the binaries are stripped before being installed, the build-id
hash will be different. This means that two different checkouts will
produce different installed binaries, even if the sources are identical.

To prevent this, set PWD=/proc/self/cwd, so that it replaces the
absolute path with the static path /proc/self/cwd. With GCC, use
-fdebug-prefix-map to remove that static path. Our clang does not yet
support this flag, but it was merged in r250094.

This does change the behavior when using gdb -- you now need to be in
$ANDROID_BUILD_TOP before gdb will load the sources.
