TargetMachine::shouldAssumeDSOLocal currently implies dso_local for such definitions.
Since clang -fno-pic add the dso_local specifier, we don't need to special case.

Adding explicit dso_local makes these tests align with the clang -fno-pic behavior

This patch partially prepares the runtime source code to be built with
-Wconversion, which should trigger warnings if any implicit conversions
can possibly change a value. For builds done with icc or gcc, all such
warnings are handled in this patch. clang gives a much longer list of
warnings, particularly for sign conversions, which the other compilers
don't report. The -Wconversion flag is commented into cmake files, but
I'm not going to turn it on. If someone thinks it is important, and wants
to fix all the clang warnings, they are welcome to.
Types of changes made here involve either improving the consistency of types
used so that no conversion is needed, or else performing careful explicit
conversions, when we're sure a problem won't arise.
Patch is a combination of changes by Terry Wilmarth and Johnny Peyton.

Due to the unfortunate way the bug could only be triggered when reading SPRG[0-3] into a register lower than %r4 with the "mfsprg %rX, 0" syntax, the tests did not detect it.
(It could not be triggered for "mfsprg0, %r2" because that pattern was already in the table, so the earlier "correct" match took effect)
As a canary, add an intentionally ambiguous "mfsprg 2, 2" and "mtsprg 2, 2" check that would have caught the problem.

The matching for intrinsic names is forgiving about types in the
name being absent or wrong. Once the intrinsic is parsed its
name will remangled to include the real types.
This commit fixes the names to have at least enough correct types
so that the name used in the test is a prefix of the canonical name.
The big missing part is the type for the VL parameter which changes
size between rv32 and rv64.
While I was in here I noticed that we were missing some tests for
double on rv32 so I fixed that by copying from rv64 and fixing up
the VL argument type.
I don't know if there's some way this changes what the vectorizers
may produce for reductions, but I have added test coverage with
3567908 and 5ced712 to show that both passes already have bugs in
this area. Hopefully this does not make things worse before we can
really fix it.
This will hopefully fix the build not becoming clean when using Ninja
1.9+. Ninja 1.9 enabled high-resolution time stamps, but pax doesn't
correctly set high-resolution timestamps on its output.
See https://github.com/nico/hack/blob/master/notes/copydir.md for a
detailed writeup of problem and alternatives.
Add command line option to read the configuration dumped by the MLIR crash
reproducer and adds those to the other command line options parsed by mlir-opt.
Simple convenience that enables `mlir-opt --run-reproducer /tmp/repro.mlir`
instead of needing to copy&paste the configuration.

Rewrite preemption.ll to dsolocal-static.ll and dsolocal-pic.ll, and add
"PIC Level" metadata.
This makes `PickValueInArray` work for `std::array<T, s>` (C++11). I've also tested the C++17 `std::array` (with compiler-deduced template parameters)

There are functions that the linker is able to automatically

rL254966 added `--sysroot=.` to prevent accidental including system headers.
It caused hassle to FreeBSD (D17383)/NetBSD. The next problem is that
we want to include `features.h` (usually `/usr/include/features.h`) to detect `__GLIBC__`.
At this point it seems that `--sysroot=.` adds lots of inconvenience so we disable it for now.
If there is a better way preventing accidental system header inclusion we can consider it again.

This is no-functional-change-intended (AFAIK, we can't
isolate this difference in a regression test).
That's because the callers should be setting the IRBuilder's
FMF field when creating the reduction and/or setting those
flags after creating. It doesn't make sense to override this
one flag alone.
This is part of a multi-step process to clean up the FMF
setting/propagation. See PR35538 for an example.
X-inseltpoison.ll is a copy of X.ll with insertelement/shufflevector's
placeholder replaced with poison.
This commit removes a few redundant functions which do not contain any
shufflevector/insertelement.
As mentioned in D93793, there are quite a few places where unary `IRBuilder::CreateShuffleVector(X, Mask)` can be used
instead of `IRBuilder::CreateShuffleVector(X, Undef, Mask)`.
Let's update them.
Actually, it would have been more natural if the patches were made in this order:
(1) let them use unary CreateShuffleVector first
(2) update IRBuilder::CreateShuffleVector to use poison as a placeholder value (D93793)
The order is swapped, but in terms of correctness it is still fine.

This patch adds support for select form of and/or.
Currently there is an ongoing effort for moving towards using `select a, b, false` instead of `and i1 a, b` and
`select a, true, b` instead of `or i1 a, b` as well.
