The LLVM dialect type system has been closed until now, i.e. did not support
types from other dialects inside containers. While this has had obvious
benefits of deriving from a common base class, it has led to some simple types
being almost identical with the built-in types, namely integer and floating
point types. This in turn has led to a lot of larger-scale complexity: simple
types must still be converted, numerous operations that correspond to LLVM IR
intrinsics are replicated to produce versions operating on either LLVM dialect
or built-in types leading to quasi-duplicate dialects, lowering to the LLVM
dialect is essentially required to be one-shot because of type conversion, etc.
In this light, it is reasonable to trade off some local complexity in the
internal implementation of LLVM dialect types for removing larger-scale system
complexity. Previous commits to the LLVM dialect type system have adapted the
API to support types from other dialects.
Replace LLVMIntegerType with the built-in IntegerType plus additional checks
that such types are signless (these are isolated in a utility function that
replaced `isa<LLVMType>` and in the parser). Temporarily keep the possibility
to parse `!llvm.i32` as a synonym for `i32`, but add a deprecation notice.

The original implementation of the OpenMP dialect to LLVM IR translation has
been relying on a stack of insertion points for delayed insertion of branch
instructions that correspond to terminator ops. This is an intrusive into
ModuleTranslation and makes the translation non-local. A recent addition of the
WsLoop translation exercised another approach where the parent op is
responsible for converting terminators of all blocks in its regions. Use this
approach for other OpenMP dialect operations with regions, remove the stack and
deduplicate the code for converting such regions.

Right now constraint/predicate traits/etc. use their "description" field as a one line human readable string. This breaks the current convention, by which a "description" may be multi-line. This revision renames the "description" field in these cases to "summary" which matches what the string is actually used as. This also unbreaks the use of TypeDefs(and eventually AttrDefs) in conjunction with existing type constraint facilities like `Optional`.

LLVM dialect type parsing and printing have been using a local stack object
forwarded between recursive functions responsible for parsing or printing
specific types. This stack is necessary to intercept (mutually) recursive
structure types and avoid inifinite recursion. This approach works only thanks
to the closedness of the LLVM dialect type system: types that don't belong to
the dialect are not allowed. Switch the approach to using a `thread_local`
stack inside the functions parsing the structure types. This makes the code
slightly cleaner by avoiding the need to pass the stack object around and, more
importantly, makes it possible to reconsider the closedness of the LLVM dialect
type system. As a nice side effect of this change, container LLVM dialect types
now support type aliases in their body (although it is currently impossible to
also use the alises when printing).

If an operation defines an optional attribute (OptionalAttr or
UnitAttr), transformations may wish to remove these attributes while
maintaining invariants established by the operation. Currently, the only
way to do this is by calling `Operation::removeAttr("attrName")`, which
requires developers to know the exact name of the attribute used by
table-gen. Furthermore, if the attribute name changes, this won't be
detected at compile time. Instead, `removeAttr` would return an empty
attribute and no errors would be raised, unless the caller checks for
the returned value.
This patch adds table gen support for generating `remove<AttrName>Attr`
methods for OptionalAttributes defined by operations.
Implementation choice: to preserve camelCase for the method's name, the
first character of an attribute called `myAttr` is changed to upper case
in order to preserve the coding style, so the final method would be
called `removeMyAttr`.
