release-1.8: Backports for julia 1.8-beta1/2 #44237

(cherry picked from commit 072c041)
Previously, there were special cases for `T[]`, `T[a]`, `T[a,b]` and `T[a,b,c]`. Together with the general case for more elements, that meant five methods to consider in cases like `T[x...]` where the length of `x` was not known at compile time. That was beyond the inference limit and such a call would be inferred as `Any`. So this change gets rid of all the special cases. The loop-based general case worked well if all arguments were of the same type, but otherwise suffered from type-instability inside the loop. Without the special cases for low element count this would be hit more often, so for the non-homogeneous case, the loop is replaced with a call to `afoldl` that basically unrolls the loop for up to 32 elements.

`std::vector::size()` returns a `size_t`, so we need to cast the int `jl_n_threads` to a `size_t` for the comparison. (cherry picked from commit 15dcd5b)

#44210) As with loop, it's hard to prove termination of recursive call automatically. But with this commit we can manually specify termination at least. ```julia Base.@assume_effects :terminates_globally function recur_termination1(x) x == 1 && return 1 1 < x < 20 || throw("bad") return x * recur_termination1(x-1) end @test fully_eliminated() do recur_termination1(12) end Base.@assume_effects :terminates_globally function recur_termination2(x) x == 1 && return 1 1 < x < 20 || throw("bad") return _recur_termination2(x) end _recur_termination2(x) = x * recur_termination2(x-1) @test fully_eliminated() do recur_termination2(12) end ```
#44282) A return type derived by const-prop' inference can be wider than that of non const-prop' inference in rare cases e.g. when there are cycles but cached result is still accurate. This commit checks if the const-prop'ed result is really more accurate than non-const result. fix Ferrite-FEM/Tensors.jl#178

On Windows, we observed occasional issues where an error within the function callback to the `open(::Function, ::Cmd)` method would cause problems due to assuming that the opened process had finished by the time the `open()` call was finished. In most cases this was true, however on Windows, it was found that we need to explicitly `wait()` upon the process object to ensure that all file handles held by the subprocess were properly closed by the time `open()` is finished.

…-thread backtrace buffer in ptls (#44116) * Fix thread-safety violation in Allocations Profiler: Re-use the shared `ptls->bt_data` buffer from the thread-local storage for the buffer, to ensure that each thread has a separate buffer. This buffer is shared with the exception throwing mechanism, but is safe to share since julia exception throwing never interleaves with allocations profiling. * Approach two: Create a separate per-thread allocations backtrace buffer. * Update src/gc-alloc-profiler.cpp Co-authored-by: Jameson Nash <vtjnash@gmail.com> * Update src/gc-alloc-profiler.cpp Co-authored-by: Jameson Nash <vtjnash@gmail.com> * fix type error (#44235) * Update src/gc-alloc-profiler.cpp Co-authored-by: Jameson Nash <vtjnash@gmail.com> Co-authored-by: Pete Vilter <7341+vilterp@users.noreply.github.com> (cherry picked from commit 4e57966)
