PR: 255570 (cherry picked from commit d409305fa3838fb39b38c26fc085fb729b8766d5) 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.

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).

This function is normally provided by libunwind, but explicitly not for the ARM Exception ABI.

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. Reviewed By: #libunwind, mstorsjo Differential Revision: https://reviews.llvm.org/D83573 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.

PR: 255570 (cherry picked from commit 4652422eb477731f284b1345afeefef7f269da50) 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.
