In translation from MLIR to another IR, run the MLIR verifier on the parsed
module to ensure only valid modules are given to the translation. Previously,
we would send any module that could be parsed to the translation, including
semantically invalid modules, leading to surprising errors or lack thereof down
the pipeline.

MLIRContext allows its users to access directly to the DialectRegistry it
contains. While sometimes useful for registering additional dialects on an
already existing context, this breaks the encapsulation by essentially giving
raw accesses to a part of the context's internal state. Remove this mutable
access and instead provide a method to append a given DialectRegistry to the
one already contained in the context. Also provide a shortcut mechanism to
construct a context from an already existing registry, which seems to be a
common use case in the wild. Keep read-only access to the registry contained in
the context in case it needs to be copied or used for constructing another
context.
With this change, DialectRegistry is no longer concerned with loading the
dialects and deciding whether to invoke delayed interface registration. Loading
is concentrated in the MLIRContext, and the functionality of the registry
better reflects its name.

This makes ignoring a result explicit by the user, and helps to prevent accidental errors with dropped results. Marking LogicalResult as no discard was always the intention from the beginning, but got lost along the way.

This will allow out-of-tree translation to register the dialects they expect
to see in their input, on the model of getDependentDialects() for passes.

These libraries are distinct from other things in Analysis in that they
operate only on core IR concepts. This also simplifies dependencies
so that Dialect -> Analysis -> Parser -> IR. Previously, the parser depended
on portions of the the Analysis directory as well, which sometimes
caused issues with the way the cmake makefile generator discovers
dependencies on generated files during compilation.

Summary:
This revision performs several cleanups on the translation infra:
* Removes the TranslateCLParser library and consolidates into Translation
- This was a weird library that existed in Support, and didn't really justify being a standalone library.
* Cleans up the internal registration and consolidates all of the translation functions within one registry.

MLIR translation tools can emit diagnostics and we want to be able to check if
it is indeed the case in tests. Reuse the source manager error handlers
provided for mlir-opt to support the verification in mlir-translate. This
requires us to change the signature of the functions that are registered to
translate sources to MLIR: it now takes a source manager instead of a memory
buffer.

Existing translations are either from MLIR or to MLIR. To support
cases like round-tripping some external format via MLIR, one must
chain two mlir-translate invocations together using pipes. This
can be problematic to support -split-input-file in mlir-translate
given that it won't work across pipes.
Motivated by the above, this CL adds another translation category
that allows file to file. This gives users more freedom.

Translations performed by mlir-translate only have MLIR on one end.
MLIR-to-MLIR conversions (including dialect changes) should be treated as
passes and run by mlir-opt. Individual translations should not care about
reading or writing MLIR and should work on in-memory representation of MLIR
modules instead. Split the TranslateFunction interface and the translate
registry into two parts: "from MLIR" and "to MLIR".
Update mlir-translate to handle both registries together by wrapping
translation functions into source-to-source convresions. Remove MLIR parsing
and writing from individual translations and make them operate on Modules
instead. This removes the need for individual translators to include
tools/mlir-translate/mlir-translate.h, which can now be safely removed.
Remove mlir-to-mlir translation that only existed as a registration example and
use mlir-opt instead for tests.

The mlir-translate tool is expected to discover individual translations at link
time. These translations must register themselves and may need the utilities
that are currently defined in mlir-translate.cpp for their entry point
functions. Since mlir-translate is linking against individual translations,
the translations cannot link against mlir-translate themselves. Extract out
the utilities into a separate "Translation" library to avoid the potential
dependency cycle. Individual translations link to that library to access
TranslateRegistration. The mlir-translate tool links to individual translations
and to the "Translation" library because it needs the utilities as well.
The main header of the new library is located in include/mlir/Translation.h to
make it easily accessible by translators. The rationale for putting it to
include/mlir rather than to one of its subdirectories is that its purpose is
similar to that of include/mlir/Pass.h so it makes sense to put them at the
same level.
