Fix cortex-a53 inclusion of files.
I accidentally broken the cortex-a53 because it directly includes files
from cortex-a15. Rather than revert that part, just copy over the files
that are needed directly so we don't run into this in the future.
Test: Built the aosp_angler-userdebug target using cortex-a53 as the
Test: arm target. Then built the bionic unit tests and ran them on
Test: an angler.

It turns out that sometimes this kernel bug can be present but not

Eliminate deadlock in forked child due to delayed resetting mutex lock
For some program implementation, the pattern like below, calling
pthread_atfork to register atfork interfaces.
pthread_atfork(&atfork_prepare, &atfork_parent, &atfork_child);
When the program is expected to reopen the shared library's handle
inherited from parent in child process. Maybe, dlclose is called in
atfork_child to release the shared library handle before reopen it.
Then, dlclose will indrectly call _cxa_finalize and finaly call
__unregister_atfork when dso is not NULL.
atfork_child() -> dlclose() -> __on_dlclose()
-> __cxa_finalize() -> __unregister_atfork(dso)
In __unregister_atfork, firstly, it try to hold the g_atfork_list_mutex
lock to operate the g_atfork_list. Due to the registered atfork_child is
executed before resetting g_atfork_list_mutex lock in child, the child
process will be blocked here because of deadlock.
Test: bionic-unit-tests32 --gtest_filter=pthread.pthread_atfork_child_with_dlclose
without the fixing, the test will be timeout.

Remove _ZTV9type_info from the version script.
We broke this ABI in L:
https://android-review.googlesource.com/c/95071/.
This ABI break is now in over half of all devices, so it's more
correct to not have it than it is to have it. It's also worth noting
that this was only ever in ARM and MIPS; it was never in x86.

Set __get_thread()->tid as part of clone().
This was previously done only in fork() and pthread_create(), but this left raw
clone() with an invalid cached tid. Since the tid is used for pthread routines,
this led to unstable behavior after clone().
