  [mlir][bazel] Fix build after changes from #183856. (#184134)

This PR fixes the bazel build breakages introduced by #183856, which
introduced a new CMake flag that wasn't set in the bazel build, thus
leading to a placeholder not being replaced and a consequent syntax
error. The fix consists of setting this value to the default (`0`),
which is how similar flags are handled.

  [CVP] Stop CVP constant propagation from destroying `llvm.assume` (#183688)

For following code sequence:
```
  %cmp = icmp ugt i64 %idx, 1
  tail call void @llvm.assume(i1 %cmp)
```
CVP may replace all use of `%cmp` with `true`, and the information about
`%idx` is lost. This commit stop CVP from doing that, so that later pass
can exploit the `llvm.assume`.

Fixes https://github.com/llvm/llvm-project/issues/90206.

  [TableGen] Allow specification of underlying type for GenericEnum (#183769)

Allow specification of the underlying C++ data type for `GenericEnum`.

I ran into this because I was trying to use a TableGen-genered enum in
`DenseSet` which requires the underlying type be specified.

  [mlir][VectorOps] Fold extract on constant_mask (#183780)

Fold `vector.extract(vector.constant_mask)` to `vector.constant_mask` if
possible.

If the static position is outside of the masked area, the pattern will
fold to a constant all-false value instead.

Dynamic positions are only supported if the mask covers the entire
vector in that dimension.

  [flang] Inline trivial scalar allocatable assignments in HLFIR-to-FIR (#183177)

For trivial scalar allocatable assignments (non-polymorphic,
non-character, non-array, non-temporary), inline the assignment directly
instead of calling the `_FortranAAssign` runtime. The inlined code
checks whether the allocatable is already allocated: if so, it stores
directly; otherwise, it allocates memory via `fir.allocmem`, stores, and
updates the box descriptor. The if-branch is necessary to handle both
cases:

```fortran
integer, allocatable :: k
allocate(k)
k = 42    ! already allocated: store directly
```

```fortran
integer, allocatable :: k
k = 42    ! not allocated: allocmem, store, update box
```

Summary:
A bunch of small issues found through linting and LLM checking.

- Broken sort comparator that violated strict weak ordering (UB)
- SearchLibrary corrupting .lib filenames via erroneous drop_front()
- Hardcoded x86_64-unknown-linux-gnu host triple in AMDGPU fatbinary
- OffloadFile loop variable shadowing its own type, causing std::move on
the type rather than the variable
- GetDeviceInput calling exit() directly instead of returning Error
- Redundant double-wrapping of DerivedArgList
- Various typo and style fixes

  [mlir][bazel] Fix build after moving AMX into X86 in #183717. (#184165)

This PR fixes the bazel build that got broken by #183717, which moved
the AMX dialect into the X86 dialect. The fix consists of replicating
the changes from the CMake files into BUILD files as usual; in this
case, mostly removing the AMX dialect targets, adding a few new
references to the corresponding X86 targets, and adding a few new
dependencies to the existing X86 targets due to the new code.
