[VPlan] Split out optimizeEVLMasks. NFC (#174925)
Addresses part of #153144 and splits off part of #166164
There are two parts to the EVL transform:
1) Convert the loop so the number of elements processed each iteration
is EVL, not VF. The IV and header mask are replaced with EVL-based
variants.
2) Optimize users of the EVL based header mask to VP intrinsic based
recipes.
(1) changes the semantics of the vector loop region, whereas (2) needs
to preserve them. This splits (2) out so we don't mix the two up, and
allows us to move (1) earlier in the pipeline in a future PR.
[NFC][Linalg] Add `matchConvolutionOpOfType` API and make `isaConvolutionOpOfType` API a wrapper (#174722)
-- This commit involves the following updates pertaining to
`isaConvolutionOpOfType` API :-
1. We don't want dilations/strides of convolution op to be returned as
pointer arguments to the API function - to tackle this we create a new
API `matchConvolutionOpOfType` which would return an optional struct of
dilations/stride.
2. To not break the original API's use case as a simple querying
functionality with true/false return - we keep `isaConvolutionOpOfType`
as a wrapper API which will invoke `matchConvolutionOpOfType` API and
return true/false depending on whether `matchConvolutionOpOfType` API
returned any value or not.
3. Dilations/strides of named convolution op are also populated now (it
was missed in the previous PRs while creating `isaConvolutionOpOfType`).
4. [Max/Min]UnsignedPool ops' body matcher now only matches unsigned int
ops (refer: https://github.com/llvm/llvm-project/pull/166070)
-- No tests are being added as all the above are NFC changes around the

[MLIR][Bufferization] Fold LoadOp only when the buffer is read only (#172595)
When we `memref.load` from a buffer, it folded to `tensor.extract` even
when the buffer was writable, causing unexpected results. For example:
```mlir
func.func @load_after_write_from_buffer_cast(%arg0: index, %arg1: index,
%arg2: tensor<?x?xf32>) -> f32 {
%0 = bufferization.to_buffer %arg2 : tensor<?x?xf32> to memref<?x?xf32>
linalg.ceil ins(%0 : memref<?x?xf32>) outs(%0 : memref<?x?xf32>)
%1 = memref.load %0[%arg0, %arg1] : memref<?x?xf32>
return %1 : f32
}
```
would fold into
```mlir
module {
func.func @load_after_write_from_buffer_cast(%arg0: index, %arg1: index, %arg2: tensor<?x?xf32>) -> f32 {
%0 = bufferization.to_buffer %arg2 : tensor<?x?xf32> to memref<?x?xf32>

[clang-repl] Use more precise search to find the orc runtime. (#175805)
The new mechanism relies on the path in the toolchain which should be
the autoritative answer. This patch tweaks the discovery of the orc
runtime from unittests where the resource directory is hard to deduce.
Should address the issue raised in #175435 and #175322
[RISCV][llvm] Support select codegen for P extension (#175741)
This is scalar condition with fixed vector true/false value, we can just
handle it same as scalars.
[RISCV][llvm] Support vselect codegen for P extension (#175744)
The only difference between vselect vs. select is condition value(a.k.a.
mask), we can select by using bitwise operation:
vselect(mask, true, false) = (mask & true) | (~mask & false)

[AMDGPU][GlobalISel] Add RegBankLegalize support for G_AMDGPU_S_MUL_*
Patch 3 of 4 patches to implement full G_MUL support in regbanklegalize.
Current mul.ll test is only partially updated and expected to fail.
It will be updated in the fourth patch.
[AMDGPU] Fix the encoding of VOP3PX2 instructions
ISA spec says `SCALE_OPSEL[0:1]` determines which parts of S3 and S4 are used, and `SCALE_OPSEL_HI[0:1]` should be zero.
