This patch adds a Bazel configuration to build lld. That includes a
BUILD.bazel file to export the libunwind headers for use by lld. Since
the lld target itself requires libxml2 (through WindowsManifest) it's
currently disabled on Buildkite and marked manual, but all the libraries
build.

Includes can now be fully managed via td_library and specified locally

Updates the Bazel configuration for
https://github.com/llvm/llvm-project/commit/ee7d20e84675. We need to
drop the dependency from llvm-tblgen to avoid a dependency cycle:
```
.-> @llvm-project//llvm:llvm-tblgen
| @llvm-project//llvm:tblgen
| @llvm-project//llvm:MC
| @llvm-project//llvm:ProfileData
| @llvm-project//llvm:Core
| @llvm-project//llvm:attributes_gen
| @llvm-project//llvm:include/llvm/IR/Attributes.inc
| @llvm-project//llvm:attributes_gen__gen_attrs_genrule
`-- @llvm-project//llvm:llvm-tblgen
```
It appears this dep was not strictly necessary though. TableGen uses MC
headers but it can get those through Support, which also exports MC
headers due to layering issues.

Add ForLoopBoundSpecialization pass, which specializes scf.for loops into a "main loop" where `step` divides the iteration space evenly and into an scf.if that handles the last iteration.
This transformation is useful for vectorization and loop tiling. E.g., when vectorizing loads/stores, programs will spend most of their time in the main loop, in which only unmasked loads/stores are used. Only the in the last iteration (scf.if), slower masked loads/stores are used.
Subsequent commits will apply this transformation in the SparseDialect and in Linalg's loop tiling.

This patch makes it possible to list a td_library as a rule's data
attribute and get its source files and all its transitive dependencies
at runtime. This is useful for, e.g. shell tests running tblgen.
Note that this is a bit different from how a "normal" (e.g. C++) library
rule would work because those have actual library outputs and the
td_library rule just bundles some source files and includes. If someone
wanted to make use of the includes, they would have to access the TdInfo
provider, but this keeps simple things simple.

This is the last instance of td_srcs in MLIR core build files. `deps` is
generally preferred. There are still some cases where `td_srcs` is
useful where creating a td_library would just be another layer of
indirection, so not (yet) dropping it entirely.

When using `llvm_zlib_external` rule with `external_zlib` attribute set to a
label referring to the main repository, like `@//third_party/zlib`, it will be
replaced with `//third_party/zlib` after template substitution. This will then
attempt to find `//third_party/zlib` within the local repository
`@llvm_zlib//third_party/zlib`, which does not exist, rather than the intended
reference back to the main repository. The issue appears to be that the
conversion of `Label` type to string with
`str(repository_ctx.attr.external_zlib)`, which is causing the main repository
qualifier to be lost.
This diff fixes the issue by changing the `external_zlib` attribute to
`attr.string` type rather than `attr.label`.
In future a more elegant solution may be possible that preserves use of the
`Label` type, depending on resolution of the issue

The `reifyReturnTypeShapesPerResultDim` method supports shape
inference for rsults that are ranked types. These are used lower in
the codegeneration stack than its counter part `reifyReturnTypeShapes`
which also supports unranked types, and is more suited for use higher
up the compilation stack. To have separation of concerns, this method
is split into its own interface.

Users should generally observe no difference as long as they don't use
unintended option forms. Behavior changes:
* `-t=d` is removed. Use `-t d` instead.
* `--demangle=false` and `--demangle=0` cannot be used. Omit the option or use `--no-demangle`. Other flag-style options don't have `--no-` forms.
* `--help-list` is removed. This is a `cl::` specific option.
* llvm-readobj now supports grouped short options as well.
* `--color` is removed. This is generally not useful (only apply to errors/warnings) but was inherited from Support.
Some adjustment to the canonical forms
(usually from GNU readelf; currently llvm-readobj has too many redundant aliases):
* --dyn-syms is canonical. --dyn-symbols is a hidden alias
* --file-header is canonical. --file-headers is a hidden alias
* --histogram is canonical. --elf-hash-histogram is a hidden alias
* --relocs is canonical. --relocations is a hidden alias
* --section-groups is canonical. --elf-section-groups is a hidden alias
OptTable avoids global option collision if we decide to support multiplexing for binary utilities.
* Most one-dash long options are still supported. `-dt, -sd, -st, -sr` are dropped due to their conflict with grouped short options.
* `--section-mapping=false` (D57365) is strange but is kept for now.
* Many `cl::opt` variables were unnecessarily external. I added `static` whenever appropriate.
