This reverts commit 5d4603a0.

The Dialect/Tensor/fold-consecutive-insert-extract-slice.mlir test is
failing when built with GCC

Discovered an issue working in StableHLO when attempting to build with `-Wall -Werror`:
https://github.com/openxla/stablehlo/pull/137

Currently, if `LLVM_USE_LLD` and `-DCMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -Wall -Werror"`
are both specified for build, the build will error with:

```
-- Performing Test CXX_SUPPORTS_CUSTOM_LINKER - Failed
CMake Error at /usr/local/google/home/gleasonk/Coding/llvm-build/lib/cmake/llvm/HandleLLVMOptions.cmake:309 (message):
  Host compiler does not support '-fuse-ld=lld'
...

$ cat <build_dir>/CMakeFiles/CMakeError.log
...
clang: error: argument unused during compilation: '-fuse-ld=lld' [-Werror,-Wunused-command-line-argument]
```

It looks like other repos have hit this same issue:
- https://github.com/golang/go/issues/41527 (mentioned in comment)
- https://github.com/iree-org/iree/pull/7450

This can be reproduced in llvm-project with the following build command:

```
# Compile command taken from https://mlir.llvm.org/getting_started/
# and modified for use case
cmake -G Ninja ../llvm \
   -DLLVM_ENABLE_PROJECTS=mlir \

This change allows the SCF LoopPipelining transform to handle ops with
nested regions within the pipelined `scf.for` body. The op and nested
regions are treated as a single unit from the transform's perspective.
This change also makes explicit the requirement that only ops whose
parent Block is the loop body Block are allowed to be scheduled by the
caller.

Out of the unratified bitmanip extensions, this one had the

[modules] Fix error "malformed or corrupted AST file: 'SourceLocation remap refers to unknown module...'".

When a framework can be found at a new location, all references to it in
the module cache become outdated. When we try to load such outdated .pcm
file, we shouldn't change any already loaded and processed modules.

If `Module` has `ASTFile`, it means we've read its AST block already and
it is too late to undo that. If `ASTFile` is `None`, there is no value
in setting it to `None` again. So we don't reset `ASTFile` in
`ModuleManager::removeModules` at all.

This patch fixes:

  clang/lib/Driver/ToolChains/PS4CPU.cpp:159:14: error: unused
  variable 'IsPS5' [-Werror,-Wunused-variable]

 Summary:
   Under code object version 5, ockl_get_local_size returns the value computed by the expression:
workgroup_id < hidden_block_count ? hidden_group_size : hidden_remainder
For functions with the attribute uniform-work-group-size=true. we can evaluate workgroup_id < hidden_block_count
as true, and thus hidden_group_size is returned for ockl_get_local_size.
  With uniform-workgroup-size=true, this work also set all remainders to zero, and if there
is reqd_work_group_size, we also set work-group-size to the required value from the metadata.

In GNU ld,

* --version skips linker input processing.
* -v and -V keep processing if there is any input file. -V has more
  information we don't support.

We currently make -V an alias for --version which skips input processing.
On many `*-freebsd` and `powerpc-*` targets, `gcc -v` passes `-V` to ld
and expects to process input. Make -V an alias for -v to provide
compatibility.

Consecutive tensor.insert_slice/tensor.extract_slice can be
created for the case like tiling convolution and then downsizing
2-D convolutions into 1-D ones. It hinders further transformations.
So adding these patterns to clean it up.

Given that bufferization is sensitive and have requirements over
the IR structure (see https://reviews.llvm.org/D132666),
these patterns are put in Transforms/ with separate entry points
for explicit collection.

This flag enables the .debug_aranges section by passing a flag to LLD
and our internal linker. This also adds a new routine that will generate
the correct flag for our internal linker or set of flags for LLD when

Here is a description of the flag from Microsoft

 The /MAPINFO option tells the linker to include the specified information in a

When processing the referenced operands in the next loop the same

Later, when these leaves are added to all partitions, the bit vector
must be resized first before the bit representing the leaf is set.
