Louis Dionne 65a422c81c [pstl] Make the default backend be the serial backend and always provide parallel policies
Summary:
Before this change, the default backend was TBB but one could disable
anything related to TBB by removing the parallel policies. This change
uses the serial backend by default and removes the ability to disable
parallel policies, which is not useful anymore.

Louis Dionne 4d88b17b3f [pstl] Remove the stdlib headers from the PSTL and move them to the tests
Summary:
PSTL should not provide those headers since they belong to the standard
library. Instead, we define a dummy standard library in the tests that
provides those headers.

Louis Dionne 1dd1b5d5f2 [pstl] Introduce forward declarations
Necessary when pstl is included from with <algorithm> and <numeric> to
prevent a partially declared standard library when pstl itself uses
algorithms from <algorithm> and <numeric>.

Also, this patch makes sure that configuration comes via standard headers.
Directly including pstl_config.h in implementation files is incompatible
with inclusion of pstl into a standard library implementation which
provides it's own library wide configuration and may configure the
library differently to the pstl_config.h used by the standalone
implementation.

Louis Dionne df32bf6b74 [pstl] Gate usage of TBB in test on whether TBB is used as a backend
__PSTL_USE_PAR_POLICIES is the wrong macro to use there, since the PSTL
could conceivably be using parallel policies but not TBB as a backend.

Louis Dionne e63f47549e [pstl] Make sure unit tests exit with a non-zero error code when they fail
The previous test system would only print errors to stderr, however CMake
(and lit) detect failure via the program returning a non-zero error code.
So all the tests would always pretend they passed.

Louis Dionne 28dc566701 [pstl] Remove some warnings when compiling with a recent Clang
There were multiple warnings for lambda captures that are unused, so
I removed those captures. I also fixed a couple of -Wsign-compare
warnings. Note that some warnings still remain, this change is not
exhaustive.

Chandler Carruth 57b08b0944 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.

Louis Dionne 5e334b516b [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.
