This means that we can now do something like:
ctx->getRegisteredDialect<LLVMDialect>();
as opposed to:
static_cast<LLVMDialect *>(ctx->getRegisteredDialect("llvm");

Currently, this is limited to operations that give access to the special registers of
NVIDIA gpus that represent block and thread indices.

Historically, the LLVM IR dialect has been using the generic form of MLIR
operation syntax. It is verbose and often redundant. Introduce the custom
printing and parsing for all existing operations in the LLVM IR dialect.
Update the relevant documentation and tests.

Example:
func @unknown_std_op() {
%0 = "std.foo_bar_op"() : () -> index
return
}
Will result in:
error: unregistered operation 'std.foo_bar_op' found in dialect ('std') that does not allow unknown operations

Dialect implementer are expected to inherit from this class when implementing their types. It does not seems right when using MLIR "from the outside" to use directly something from `mlir::detail::`.

Previously we emit both op declaration and definition into one file and include it
in *Ops.h. That pulls in lots of implementation details in the header file and we
cannot hide symbols local to implementation. This CL splits them to provide a cleaner
interface.
The way how we define custom builders in TableGen is changed accordingly because now
we need to distinguish signatures and implementation logic. Some custom builders with
complicated logic now can be moved to be implemented in .cpp entirely.

This CL changes dialect op source files (.h, .cpp, .td) to follow the following
convention:
<full-dialect-name>/<dialect-namespace>Ops.{h|cpp|td}
Builtin and standard dialects are specially treated, though. Both of them do
not have dialect namespace; the former is still named as BuiltinOps.* and the
latter is named as Ops.*.
Purely mechanical. NFC.

LLVM IR types are defined using MLIR's extendable type system. The dialect
provides the only type kind, LLVMType, that wraps an llvm::Type*. Since LLVM
IR types are pointer-unique, MLIR type systems relies on those pointers to
perform its own type unique'ing. Type parsing and printing is delegated to
LLVM libraries.
Define MLIR operations for the LLVM IR instructions currently used by the
translation to the LLVM IR Target to simplify eventual transition. Operations
classes are defined using TableGen. LLVM IR instruction operands that are only
allowed to take constant values are accepted as attributes instead. All
operations are using verbose form for printing and parsing.
