[GlobalISel] Introduce G_BUILD_VECTOR, G_BUILD_VECTOR_TRUNC and G_CONCAT_VECTOR opcodes. These opcodes are intended to subsume some of the capability of G_MERGE_VALUES, as it was too powerful and thus complex to add deal with throughout the GISel pipeline. G_BUILD_VECTOR creates a vector value from a sequence of uniformly typed scalar values. G_BUILD_VECTOR_TRUNC is a special opcode for handling scalar operands which are larger than the destination vector element type, and therefore does an implicit truncate. G_CONCAT_VECTOR creates a vector by concatenating smaller, uniformly typed, vectors together. These will be used in a subsequent commit. This commit just adds the initial infrastructure.

Try to organize MachineVerifier tests The Verifier is separate from the MachineVerifier, so move it to a different directory. Some other verifier tests were scattered in target codegen tests as well (although I'm sure I missed some). Work towards using a more consistent naming scheme to make it clearer where the gaps still are for generic instructions. llvm-svn: 354138
