Initial PSTL commit The initial commit of the Parallel STL upstream (under LLVM umbrella) based on Parallel STL 20181204 open source release, which is available by https://github.com/intel/parallelstl Author: Mikhail Dvorskiy <mikhail.dvorskiy@intel.com> Differential Revision: https://reviews.llvm.org/D55889 llvm-svn: 349653

Update more file headers across all of the LLVM projects in the monorepo to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648

[CMake] Bump CMake minimum version to 3.13.4 This upgrade should be friction-less because we've already been ensuring that CMake >= 3.13.4 is used.

[pstl] Initial integration with LLVM's CMake Summary: This commit adds a check-pstl CMake target that will run the tests we currently have for pstl. Those tests are not using LLVM lit yet, but switching them over should be a transparent change. With this change, we can start relying on the `check-pstl` target for workflows and CI. Note that this commit purposefully does not support the pre-monorepo layout (with subprojects in projects/), since LLVM is moving towards the monorepo layout anyway.

[pstl] Initial implementation of OpenMP backend, on behalf of Christopher Nelson nadiasvertex@gmail.com Phabricator Review: https://reviews.llvm.org/D99836 A couple of parallel patterns still remains serial - "Parallel partial sort", and "Parallel transform scan" - there are //TODOs in the code.

[pstl] Allow customizing whether per-TU insulation is provided Like we do in libc++, PSTL needs the ability to constrain ABI-unstable symbols to each translation unit. This is OFF by default (like for libc++), because most people don't care about this and there is a cost associated to enabling the option (code bloat because templates are not deduped across TUs). I'm using '#pragma clang attribute push' to avoid marking each declaration with an attribute, which quickly becomes difficult to maintain. llvm-svn: 368684
