In debug info, we expect variables to have location info if they are used and we don't want location info for functions that are not used. However, if an unused function is inlined, we could have the scenario where a function is not in the final binary but its static variable is in the final binary. Ensure that variables in the final binary have location debug info even if their scope was inlined.

Also add `--implicit-check-not` to a test for clarity.

Introduce a FreeBSDKernel plugin that provides the ability to read
FreeBSD kernel core dumps.  The plugin utilizes libfbsdvmcore to provide
support for both "full memory dump" and minidump formats across variety
of architectures supported by FreeBSD.  It provides the ability to read
kernel memory, as well as the crashed thread status with registers
on arm64, i386 and x86_64.

Disable automatic issue labeling for forks, so that it does not

If a loop isn't forced to be unrolled, we want to avoid unrolling it when there
is an explicit unroll-and-jam pragma. This is to prevent automatic unrolling

When possible, optimize TRUNCATE to generate Wasm SIMD narrow

The library is always build using C++20 so these guards are not needed.

As noted in the code comment, we might want to simply give up on this select
transform completely (given how many exceptions there are already and the
risk of future conflicts), but for now, carve out one more bailout to
avoid an infinite loop.

The transform can require an optional shuffle instruction to be sound,
so we need to use Builder to create all values and then replace the
original instruction with whatever that final value is.

Bazel support is through utils/bazel, and the BUILD files in `benchmark`
just complicate downstream integrates for bazel based builds.

As explained in https://stackoverflow.com/a/70339311/627587, the fact
that shrink_to_fit wasn't defined as inline lead to issues when explicitly

This reverts commit ac60263a.

It looks like the test fails on certain non-Darwin system, even though
the triple is explicitly set to macos. Revert while I investigate.

This change is split out from D115497 to add the option
independently from the switch of the default value.

The LangRef incorrectly says that if no exact match is found when
seeking alignment for a vector type, the largest vector type smaller
than the sought-after vector type. This is incorrect as vector types
require an exact match, else they fall back to reporting the natural
alignment.

The corrected rule was not added in its place, as rules for other types
(e.g., floating-point types) aren't documented.

A unit test was added to demonstrate this.

MIPS64 little endian target has a "special" encoding of `r_info`
relocation record field. Instead of one 64-bit little endian number, it
is a little endian 32-bit number followed by a 32-bit big endian number.
For correct reading and writing such fields we must provide information
about target machine into the corresponding routine. This patch does
this for the `llvm-objcopy` tool and fix handling of MIPS64 little
endian files.

The bug was reported in the issue #52647.

Changes the preliminary multinode analysis:
1. Introduced scores for reversed loads/extractelements.
2. Improved shallow score calculation.
3. Lowered the cost of external uses (no need to consider it several times, just ones).
4. The initial lane for analysis is the one with the minimal possible
   reorderings.

These changes in general shall reduce compile time and improve the
reordering in many cases.
