Fangrui Song 68edf39ede [TargetMachine] Simplify shouldAssumeDSOLocal by processing ExternalSymbolSDNode early
The function accrues many `GV` nullness checks. Process `!GV`

Also improve a comment added in r327198 (intrinsics is a subset of
ExternalSymbolSDNode).

Intended to be NFC.

Joachim Protze a148216b31 [OpenMP][OMPT] Fix OMPT return address guard for gomp interface
D91692 missed various locations in kmp_gsupport, where the scope for
OMPT_STORE_RETURN_ADDRESS is too narrow, i.e. the scope ends before the OMPT
callback is called in some nested function.

This patch fixes the scoping issue, so that all OMPT tests pass, when the
tests are built with gcc.

Zbigniew Sarbinowski e6c89a499d [SystemZ][ZOS] Fix the usage of pthread_t within libc++
This is the the minimal change introduced in [[ https://reviews.llvm.org/D88599 | D88599 ]]  to unblock the controversial change and discussion of proper separation between thread from thread id which will continue in D88599.

This patch will address the differences of definition of pthread_t on z/OS vs. Linux and other OS. Main trick to make the code work on z/OS relies on redefining libcpp_thread_id type and _LIBCPP_NULL_THREAD macro. This is necessary to separate initialization of libcxx_thread_id from the one of __libcxx_thread_t;

River Riddle 47364f95e8 [mlir][IR] Move the storage for results to before the Operation instead of after.
Trailing objects are really nice for storing additional data inline with the main class, and is something that we heavily take advantage of for Operation(and many other classes). To get the address of the inline data you need to compute the address by doing some pointer arithmetic taking into account any objects stored before the object you want to access. Most classes keep the count of the number of objects, so this is relatively cheap to compute. This is not the case for results though, which have two different types(inline and trailing) that are not necessarily as cheap to compute as the count for other objects. This revision moves the storage for results to before the operation and stores them in reverse order. This allows for getting results to still be very fast given that they are never iterated directly in order, and also greatly improves the speed when accessing the other trailing objects of an operation(operands/regions/blocks/etc).

This reduced compile time when compiling a decently sized mlir module by about ~400ms, or 2.17s -> 1.76s.

Fangrui Song 961f31d8ad [TargetMachine] Don't imply dso_local on global variable declarations in Reloc::Static model
clang/lib/CodeGen/CodeGenModule sets dso_local on applicable global variables,
we don't need to duplicate the work in TargetMachine:shouldAssumeDSOLocal.
(Actually the long-term goal (started by r324535) is to remove as much
additional implied dso_local in TargetMachine:shouldAssumeDSOLocal as possible.)

By not implying dso_local, we will respect dso_local/dso_preemptable specifiers
set by the frontend. This allows the proposed -fno-direct-access-external-data
option to work with -fno-pic and prevent copy relocations.

This patch should be NFC in terms of the Clang behavior because the case we
don't set dso_local is a case Clang sets dso_local. However, some tests don't
set dso_local on some `external global` and expose some differences. Most tests
have been fixed to be more robust in previous commits.

Arthur O'Dwyer b8bc4e153f [libc++] Update the commented "synopsis" in <algorithm> to match current reality.
The synopsis now reflects what's implemented. It does NOT reflect
all of what's specified in C++20. The "constexpr in C++20" markings
are still missing from these 12 algorithms, because they are still
unimplemented by libc++:

    reverse partition sort nth_element next_permutation prev_permutation
    push_heap pop_heap make_heap sort_heap partial_sort partial_sort_copy

All of the above algorithms were excluded from [P0202].

All of the above algorithms were made constexpr in [P0879] (along with
swap_ranges, iter_swap, and rotate — we've already implemented those three).

Arthur O'Dwyer 14098cf6c0 [libc++] [P0202] constexpr set_union, set_difference, set_symmetric_difference, merge
These had been waiting on the ability to use `std::copy` from
constexpr code (which in turn had been waiting on the ability to
use `is_constant_evaluated()` to switch between `memmove` and non-`memmove`
implementations of `std::copy`). That work landed a while ago,
so these algorithms can all be constexpr in C++20 now.

Simultaneously, update the tests for the set algorithms.

- Use an element type with "equivalent but not identical" values.
- The custom-comparator tests now pass something different from `operator<`.
- Make the constexpr coverage match the non-constexpr coverage.
