Translates a mlir::BlockArgument to an mlir::Value more directly
representing the entity or expression to which the block argument
refers, or null if not applicable for the statement in question.
The macro is no longer necessary: the code now ensures we never
need to assign anything to an array, which would be ill-advised
nevertheless given that array-typed rvalues in C immediately
decay to pointers.

Teach CliftToCEmitter how to emit assignments and bitcasts whose
target type is an array, by emitting calls to the new
assign_array and bit_cast_to_array macros. The shape of the call
encodes the element type and the number of elements, which is what
the macros need to expand correctly.
`mlir::Type` is now used as the default C++ type for representing all
MLIR types, even when `ValueType` would be a valid constraint, unless
doing so provides a clear benefit in that specific context.
* PrimitiveType is now an interface.
* VoidKind is now VoidType.
* FloatKind is now FloatType.
* The integer kinds are now IntegerType with IntegerKind.
* DecayOp - array or function to pointer decay. Not shown in C.
* BitCastOp - bit-preserving conversion. Emitted as bit_cast if
necessary.
* ExtendOp - zero- or sign-extending conversion from any integer type to
any wider integer type.
* TruncateOp - truncating conversion from any integer type to any
narrower integer type.
* PtrResizeOp - resizes a pointer without changing its pointee type.
