[AMDGPU][NFC] Use RegisterOperand instead of RegisterClass (#180574)
RegisterOperand has decoder/other methods and is generally preferred for
operands.
[Windows][Support] Add helper to expand short 8.3 form paths (#178480)
Windows supports short 8.3 form filenames (for example,
`compile_commands.json` -> `COMPIL~1.JSO`) for legacy reasons. See:
https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#short-vs-long-names
Such paths are not unusual because, on Windows, the system temporary
directory is commonly derived from the `TMP`/`TEMP` environment
variables. For historical compatibility reasons, these variables are
often set to short 8.3 form paths on systems where user names exceed
eight characters.
Introduce `windows::makeLongFormPath()` to convert paths to their long
form by expanding any 8.3 components via `GetLongPathNameW`.
As part of this change:
- Extended-length path prefix handling is centralized by adding
`stripExtendedPrefix()` and reusing it in `realPathFromHandle()`.
- `widenPath()` is cleaned up to use shared prefix constants.

[MLIR] Make the verification order fixed in DynamicOpTraitList (#180758)
Currently we use `DenseMap` in `DynamicOpTraitList` to store traits and
iterate over the `DenseMap`, and we found that the order is not fixed
and we also cannot control verification order.
In this PR we use `MapVector` to preserve the insertion order so that
the verification order over traits can be fixed and users can tune the
verification order.
[VPlan] Fix convertToPhisToBlends folding non poison blend to poison (#180686)
This fixes a miscompile in #180005 where we didn't check that the first
incoming value isn't poison.
We should use the first non-poison incoming value if it exists, or just
poison if all the incoming values are poison.
[LoopVectorizer] Rename variable (NFC). (#180585)
Since TargetTransformInfo::enableAggressiveInterleaving(bool
HasReductions) takes the HasReductions argument, the LoopVectorizer
should save its returned value in a variable called AggressivelyInterleave
instead of AggressivelyInterleaveReductions.
Change init entrypoint to always go through the filterChange() pipeline, but have a fast path in there that initializes without a filter. This adds the filter immediately when loading with the page with the URL hash
[NFC][TableGen] Adopt CodeGenHelpers in GobalISel emitters (#180143)
Add specific emitters for `#ifdef` and `#ifndef` based guards and adopt
them and other CodeGenHelpers in Global ISel emitters.
devel/kBuild: fix build on powerpc*
Add architecture-specific code to kHlpAssertBreakpoint() so that
the build progresses on powerpc-derived platforms.
This whole thing can probably be replaced with just
#define kHlpAssertBreakpoint __builtin_trap
but I have decided for the minimal invasive change for now.

textproc/comparator: Find common sections in source trees
comparator is a program for rapidly finding common segments in large
source-code trees. See the manual page for instructions. It comes with
a filtering postprecessor, filterator.
