Move the bail out logic to before constructing the Result and Lane
vectors. This is both potentially faster, and avoids calling

Summary:
According to OpenMP, During execution of an iteration of a worksharing-loop or a loop nest within a worksharing-loop, simd, or worksharing-loop SIMD region, a thread must not execute more than one ordered region corresponding to an ordered construct without a depend clause.
Need to report an error in this case.

Some tests were missing alignment info. Subsequent changes properly
preserve the set alignment. Set it properly beforehand, to avoid
unnecessary test changes.
Before this change we showed all result groups with a code that was not
explicitly hard-coded set. This set missed the FLAKYPASS result code.
Let's generalize the code to always show failures and the additionally
requested result codes.
Summary:
We're trying to use the --config options to pass distro specific
options for Fedora via the CFLAGS variable. However, some projects
end up using the CFLAGS variable multiple times in their command line,
which leads to an error when --config is used.
This patch resolves this issue by allowing more than one --config option
on the command line as long as the file names are the same.

Recent work has introduced support for constructing loops via `::build` with
callbacks that construct loop bodies using only the core OpBuilder. This is now
supported on all loop types that Linalg lowers to. Refactor LoopNestBuilder in
Linalg to rely on this functionality instead of using a custom EDSC-based
approach to creating loop nests.
The specialization targeting parallel loops is also simplified by factoring out
the recursive call into a separate static function and considering only two
alternatives: top-level loop is parallel or sequential.
This removes the last remaining in-tree use of edsc::LoopBuilder, which is now
deprecated and will be removed soon.

Similarly to `scf::ForOp`, introduce additional `function_ref` arguments to
`::build` functions of SCF `ParallelOp` and `ReduceOp`. The provided functions
will be called to construct the body of the respective operations while
constructing the operation itself. Exercise them in LoopUtils.

The issue is that our custom input reader doesn't handle EOF. According
to the Python documentation, file.readline always includes a trailing
newline character unless the file ends with an incomplete line. An empty
string signals EOF. This patch raises an EOFError when that happens.

Generalize scalarization (recently enhanced with D80885)
to allow compares as well as binops.
Similar to binops, we are avoiding scalarization of a loaded
value because that could avoid a register transfer in codegen.
This requires 1 extra predicate that I am aware of: we do not
want to scalarize the condition value of a vector select. That
might also invert a transform that we do in instcombine that
prefers a vector condition operand for a vector select.
I think this is the final step in solving PR37463:

The Standard documents the signature of std::advance as
template <class Iter, class Distance>
constexpr void advance(Iter& i, Distance n);
Furthermore, it does not appear to put any restriction on what the type
of Distance should be. While it is understood that it should usually
be std::iterator_traits::difference_type, I couldn't find any wording
that mandates that. Similarly, I couldn't find wording that forces the
distance to be a signed type.
This patch changes std::advance to accept any type in the second argument,
which appears to be what the Standard mandates. We then coerce it to the
iterator's difference type, but that's an implementation detail.

When selecting 32 b -> 64 b G_ZEXTs, we don't have to always emit the extend.
If the instruction feeding into the G_ZEXT implicitly zero extends the high
half of the register, we can just emit a SUBREG_TO_REG instead.

Summary:
This revision replaces MatmulOp, now that DRR rules have been dropped.
This revision also fixes minor parsing bugs and a plugs a few holes to get e2e paths working (e.g. library call emission).
During the replacement the i32 version had to be dropped because only the EDSC operators +, *, etc support type inference.
Deciding on a type-polymorphic behavior, and implementing it, is left for future work.

It also updates cases where an alignment of 16 was specified, instead of

This patch upstreams support for BFloat Matrix Multiplication Intrinsics
and Code Generation from __bf16 to AArch64. This includes IR intrinsics. Unittests are
provided as needed. AArch32 Intrinsics + CodeGen will come after this
patch.
This patch is part of a series implementing the Bfloat16 extension of
the
Armv8.6-a architecture, as detailed here:

Summary:
EOF macro token coming from a PCH file on macOS while marked as literal,
doesn't contain any literal data. This causes crash on every project

This commit doesn't resolve the problem with PCH (maybe it was
designed like this for a purpose) or with `tryExpandAsInteger`, but
rather simply shoots off a crash itself.
