[mlir] Add a new builtin `unrealized_conversion_cast` operation An `unrealized_conversion_cast` operation represents an unrealized conversion from one set of types to another, that is used to enable the inter-mixing of different type systems. This operation should not be attributed any special representational or execution semantics, and is generally only intended to be used to satisfy the temporary intermixing of type systems during the conversion of one type system to another. This operation was discussed in the following RFC(and ODM): https://llvm.discourse.group/t/open-meeting-1-14-dialect-conversion-and-type-conversion-the-question-of-cast-operations/ Differential Revision: https://reviews.llvm.org/D94832 2021-01-21 08:17:26 +08:00			`// RUN: mlir-opt %s -split-input-file -verify-diagnostics`

[mlir] Set the namespace of the BuiltinDialect to 'builtin' Historically the builtin dialect has had an empty namespace. This has unfortunately created a very awkward situation, where many utilities either have to special case the empty namespace, or just don't work at all right now. This revision adds a namespace to the builtin dialect, and starts to cleanup some of the utilities to no longer handle empty namespaces. For now, the assembly form of builtin operations does not require the `builtin.` prefix. (This should likely be re-evaluated though) Differential Revision: https://reviews.llvm.org/D105149 2021-07-29 04:32:47 +08:00			`"builtin.unrealized_conversion_cast"() : () -> ()`
