I failed to convince the compiler/linker to just refrain (via factoring out,
attribute `noinline`, or meddling with `--icf=none`), but luckily I noticed
that we should have CHECK_FP in each function for a better error message,
and the distinct error messages keep the two functions apart.
(Also add a missing CHECK_FP to `clearerr_unlocked`.)

Use a global gtest isolation runner rather than the custom one in
bionic.
Test: Ran all unit tests and verified same behavior before and after.

During the review of the script that generates /vendor/etc/passwd, it
was suggested that the shell be /vendor/bin/sh instead of the typical
/system/bin/sh. This has subsequently caused bionic unit tests to
fail, since they always check that the shell is set to /system/bin/sh.
In the spirit of that review, libc is modified to return
/vendor/bin/sh for the OEM AID ranges and the test is updated to
expect this.

cc_objects are getting support for STL headers, disable them for

Originally a BSD extension, now in glibc too. We've used it internally
for a while.

Disable -Wmemset-transposed-args to ensure that FORTIFY still works
without it. Also, we can finally enable checking for
FLT_HAS_SUBNORM/DBL_HAS_SUBNORM/LDBL_HAS_SUBNORM now that those are
available in Clang.

It should be possible to run the benchmarks on any device, including
past and future ones, and sticking to NDK libraries ensures that.

Make sure that TLS_SLOT_TSAN is always available and correctly set up in
HWASan-instrumented functions by setting up the tls register and running hwasan
initialization (__hwasan_init in the main thread and __hwasan_thread_enter in
secondary) early enough.
This is needed to accomodate a change in HWASan: https://reviews.llvm.org/D52249

These system calls are required by Breakpad for crash reporting.
WebViews are spawned from the webview_zygote, which itself is spawned
from the app_process zygote. The webview_zygote gets the SYSTEM seccomp
policy applied because it is not an app, and so the WebView sandboxed
processes inherit that policy.
In Ifd8a85b0de2eb6f2a76a6458570fc03b020a90ab, these system calls were
moved from COMMON to APP, which breaks Breakpad/crash reporting for
WebView sandboxed processes.
