[mlir][AMDGPU] Split the dialect declaration (NFC)
Introduce a self-contained dialect declaration so RegisterAllDialects does not
need the generated AMDGPU operation umbrella.
Across five controlled rebuilds of the affected TU, median instructions fell
from 71.757B to 70.331B (-1.987%) and median wall time fell from 11.01s to
10.77s (-2.180%).

[mlir][Func] Split the dialect declaration (NFC)
Introduce a self-contained dialect declaration and use it in ten configured
consumers that do not need the generated operation umbrella.
Across three controlled -j16 rebuilds of the affected TUs, median instructions
fell from 224.883B to 220.787B (-1.821%) and median wall time fell from 8.44s
to 8.31s (-1.540%).

[mlir][Bufferization] Split the dialect declaration (NFC)
Introduce a self-contained dialect declaration and use it in four consumers
that do not need the generated operation umbrella.
Across three controlled serial rebuilds of the affected TUs, median
instructions fell from 97.470B to 94.887B (-2.650%) and median wall time fell
from 15.20s to 14.70s (-3.289%). Three -j16 runs confirmed a 2.623% reduction
in instructions, with wall time improving 0.722% on the parallel critical path.

[LoongArch] Generate more PCRel relocations for resolvable sub-symbols
Use PC-relative relocations when the sub-symbol offset can be resolved
during assembly, avoiding ADD/SUB relocation pairs.

[flang] Fold fir.convert of an integer constant between integer types (#222188)
`fir::ConvertOp::fold` doesn't handle an integer constant converted to
another integer type. `ForwardConstantConvertPattern` covers the
neighboring case where the result is `index`, so `fir.convert %c10_i32 :
(i32) -> index` already canonicalizes to an index constant while
`fir.convert %c1_i32 : (i32) -> i64` does not. This PR adds the
integer-to-integer case.
The width change follows the rules codegen applies to a non-constant
operand (`CodeGen.cpp`'s integer-to-integer conversion): narrowing
truncates, widening zero-extends an i1 or unsigned source and
sign-extends anything else. The result must be signless because the
constant materialises as an `arith.constant`, which only accepts
signless integers.
It composes with `arith::IndexCastOp::fold`, so a value widened then
cast to `index` collapses to one index constant, and it lets other
patterns see through the constant: with a literal shift,

R-cran-shape provides functions for plotting graphical shapes, colors
and more. Required by databases/R-cran-glmnet since 2.0.
[Offloading] Add support for compressed OffloadBinary types
Summary:
Offload binaries are used to store many heterogenous architectures into
a singel offloading blob. These lists can get very large so this PR adds
the option to compress them with the LLVM provided compression
libraries.
The implementation is quite simple, we simply compress all the buffers
after the header into a single compressed blob, then re-construct the
header. Extracting is the reverse.
The biggest change is that the offload binary now **owns** the memory,
whereas before we simply took a reference to it. This is necessary
because the decompression must create new memory compared to what the
user provided. This adds an extra copy internally, but it also
simplifies the V2 additions.
This does not wire up any clang/HIP support, just providing the
functionality.
[LLVM] Add zstd compressed frame magic to LLVM magic
Summary:
ZSTD uses magic to indentify compressed frames in the bitstream. Add
this as a recognized file magic type so that we can identify compressed
streams that LLVM creates.
