Disable strict-fp for powerpcspe, as it does not work properly yet
Merge commit 5c18d1136665 from llvm git (by Qiu Chaofan)
[SPE] Disable strict-fp for SPE by default
As discussed in PR50385, strict-fp on PowerPC SPE has not been
handled well. This patch disables it by default for SPE.

Apply upstream libc++ fix to allow building with devel/xxx-xtoolchain-gcc
Merge commit 52e9d80d5db2 from llvm git (by Jason Liu):
[libc++] add `inline` for __open's definition in ifstream and ofstream
Summary:
When building with gcc on AIX, it seems that gcc does not like the
`always_inline` without the `inline` keyword.
So adding the inline keywords in for __open in ifstream and ofstream.
That will also make it consistent with __open in basic_filebuf
(it seems we added `inline` there before for gcc build as well).

Undefine HAVE_(DE)REGISTER_FRAME in llvm's config.h on arm
Otherwise, the lli tool (enable by WITH_CLANG_EXTRAS) won't link on arm,
stating that __register_frame is undefined. This function is normally
provided by libunwind, but explicitly not for the ARM Exception ABI.

Revert libunwind change to fix backtrace segfault on aarch64
Revert commit 22b615a96593 from llvm git (by Daniel Kiss):
[libunwind] Support for leaf function unwinding.
Unwinding leaf function is useful in cases when the backtrace finds a
leaf function for example when it caused a signal.
This patch also add the support for the DW_CFA_undefined because it marks
the end of the frames.
Ryan Prichard provided code for the tests.

Reland with limit the test to the x86_64-linux target.
Bisection has shown that this particular upstream commit causes programs
using backtrace(3) on aarch64 to segfault. This affects the lang/rust
port, for instance. Until we can upstream to fix this problem, revert
the commit for now.

compilert-rt: build out-of-line LSE atomics helpers for aarch64
Both clang >= 12 and gcc >= 10.1 now default to -moutline-atomics for
aarch64. This requires a bunch of helper functions in libcompiler_rt.a,
to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel".
(Note: of course you can use -mno-outline-atomics as a workaround too,
but this would negate the potential performance benefit of the faster
LSE instructions.)
Bump __FreeBSD_version so ports maintainers can easily detect this.
