  -----------
  [mlir][llvmir] Import intrinsics with attributes from LLVMIR.

The revision adds support to specify custom import functions for
LLVM IR intrinsics with immediate arguments that translate to MLIR
attributes. It takes an approach similar to the MLIR to LLVM translation
that uses a tablegen defined build method. The default implementation
of this newly introduced "mlirBuilder" assumes all intrinsic arguments
translate to operands. Specific intrinsics, such as
llvm.lifetime.start/stop then define a custom builder that converts
their immediate arguments to MLIR attributes.

Depends on D135349
