Cherry picked from LLVM commit 801b519dfd01e21da0be17aa8f8dc2ceb0eb9e77.
In powerpc64-unknown-linux-musl, signal.h does not include asm/ptrace.h,
which causes "member access into incomplete type 'struct pt_regs'"
errors. Include the header explicitly to fix this.
Also in sanitizer_linux_libcdep.cpp, there is a usage of TlsPreTcbSize
which is not defined in such a platform. Guard the branch with macro.
The following patch is result of libsanitizer/merge.sh
from c425db2eb558c263 (yesterday evening).
Bootstrapped/regtested on x86_64-linux and i686-linux (together with
the follow-up 3 patches I'm about to post).
BTW, seems upstream has added riscv64 support for I think lsan/tsan,
so if anyone is willing to try it there, it would be a matter of
copying e.g. the s390*-*-linux* libsanitizer/configure.tgt entry
to riscv64-*-linux* with the obvious s/s390x/riscv64/ change in it.
The libsanitizer build has been broken on Solaris 11.3 by the latest
import. An upstream patch to fix this has now been committed:
[sanitizer_common] Support Solaris < 11.4 in GetStaticTlsBoundary
https://reviews.llvm.org/D120059
I'd like to cherry-pick it into libsanitizer, too.
Bootstrapped without regressions on sparc-sun-solaris2.11,
i386-pc-solaris2.11 (both Solaris 11.3 and 11.4), and
x86_64-pc-linux-gnu.

* sanitizer_common/sanitizer_linux_libcdep.cpp,
sanitizer_common/sanitizer_solaris.h:: Cherry-pick
llvm-project revision 3776db9a4fd2080d23d6a5f52e405eea44558761.
I've cherry-picked following fix from llvm-project. Recent glibcs
have _thread_db_sizeof_pthread symbol variable which contains the
size of struct pthread, so that sanitizers don't need to guess that
and risk that it will change again.

* sanitizer_common/sanitizer_linux_libcdep.cpp: Cherry-pick
llvm-project revision ef14b78d9a144ba81ba02083fe21eb286a88732b.
Merged from revision b638b63b99d66786cb37336292604a2ae3490cfd.
The patch successfully bootstraps on x86_64-linux-gnu and
ppc64le-linux-gnu. I also tested ppc64-linux-gnu that exposed:
https://reviews.llvm.org/D80864 (which is fixed on master).
Abidiff looks happy and I made UBSAN and ASAN bootstrap on
x86_64-linux-gnu.
I'm planning to do merge from master twice a year, once now and
next time short before stage1 closes.
I am going to install the patches as merge from master is obvious
and I haven't made anything special.
