Replace the existing __attribute__((destructor)) function,
unregister_emutls_key, with a function that something else must call
explicitly. We don't want the pthread key deleted at program exit, because
it's unnecessary and because it may delete the key before other tls-using
cleanup code runs. Exposing __emutls_unregister_key allows limiting the
cleanup to dlclose (e.g. by calling it only from crtbegin_so.c).
Reset emutls_key_created so multiple calls to __emutls_unregister_key are
safe.

dl_iterate_phdr returns a 0 load_base for a PIE executable when it should
return the address where the executable was loaded (e.g. the load base or
load bias). Recalculate the load base when it is zero. This recalculation
should work on any ELF file with a PT_PHDR segment -- it will calculate 0
for a non-PIE executable.
The load base is added to an ELF virtual address to produce a run-time
address. Recalculate it by subtracting the PT_PHDR's virtual address from
its run-time address.

With Android/Bionic, delay deallocation to round 2 of 4. It must run after
C++ thread_local destructors have been called, but before the final 2
rounds, because emutls calls free, and jemalloc then needs another 2
rounds to free its thread-specific data.

This backports upstream patch to add support of vrdn<*>_f64 intrinisics
for aarch64. This is needed because glibc 2.27 uses some of them.

Newer glibc removes 'struct' tag from ucontext_t. Because of this, gcc
failed to bootstrap with newer glibc. This patch from upstream fixes
that.
BUG=chromium:834385
TEST=sudo emerge sys-devel/gcc passes with newer glibc installed.
commit 14c2f22a1877f6b60a2f7c2f83ffb032759456a6
Author: jsm28 <jsm28@138bc75d-0d04-0410-961f-82ee72b054a4>
Date: Tue Jul 4 10:22:56 2017 +0000
Use ucontext_t not struct ucontext in linux-unwind.h files.
Current glibc no longer gives the ucontext_t type the tag struct
ucontext, to conform with POSIX namespace rules. This requires
various linux-unwind.h files in libgcc, that were previously using
struct ucontext, to be fixed to use ucontext_t instead. This is
similar to the removal of the struct siginfo tag from siginfo_t some
years ago.
This patch changes those files to use ucontext_t instead. As the
standard name that should be unconditionally safe, so this is not
restricted to architectures supported by glibc, or conditioned on the
glibc version.
Tested compilation together with current glibc with glibc's
build-many-glibcs.py.

Currently in emutls.c 'emutls_key_created' is defined within part
of an ifdef, but is accessed outside the ifdef, which can cause
issues in builds where the ifdef is not taken. This CL moves
the #endif to include the new function that accesses 'emutls_key_created'
so that all references to it are within the defining if-def.

Remove the 'throw()' from posix_memalign declaration if __GLIBC__ is

conflicting decl error). Can't remove 'throw ()' altogether, because
it IS in glibc's stdlib.h, which this has to match in ChromeOS.

With the changes that unified the Android & ChromeOS GCC compiler,
some of the conditional changes introduced with the enable-bionic-libs
flags were causing libgnustl_shared.so to be generated with symbol
versions and symbolic links, which broke certain things.

The previous version of the unified GCC compiler (Android & ChromeOS)
caused some ChromeOS tests to fail. It also caused an Android NDK
test case to fail. This CL fixes those problems. In particular it
does the following:
- Fix some file formatting errors from previous unification patch.
- Update ChangeLog files to reflect Android backport patches.
- Find and incorporate a few missing pieces from the following backports
backports from trunk r221007, r221675, r222011, r212011, r214942,
r214957, r215012, r215016, r218115, r218733, r218746, r220491. This
involved small changes in the following files:
gcc/cfghoks.c
gcc/cfgloop.c
gcc/cfgloop.h
gcc/except.c
gcc/loop-init.c
gcc/omp-low.c
- Fix minor Android test case regression introduced in the previous
unification patch.

Theses changes are intended to restore the ability to build
toolchain/gcc cross compiler for non-Android targets (in this specific
case, to allow us to compile toolchain/gcc as part of the mingw-w64
build).
What has happened over time is that references android-specific
synbols and constructs have crept into the non-target-specific
portions of the gcc code. I've done my best to push these things
back into the config/* subtree.
