Daniel Sanders 7a289d0e39 [mips][msa] Implemented build_vector using ldi, fill, and custom SelectionDAG nodes (VSPLAT and VSPLATD)
Note: There's a later patch on my branch that re-implements this to select
build_vector without the custom SelectionDAG nodes. The future patch avoids
the constant-folding problems stemming from the custom node (i.e. it doesn't
need to re-implement all the DAG combines related to BUILD_VECTOR).

Changes to MIPS specific SelectionDAG nodes:
* Added VSPLAT
    This is a special case of BUILD_VECTOR that covers the case the
    BUILD_VECTOR is a splat operation.
* Added VSPLATD
    This is a special case of VSPLAT that handles the cases when v2i64 is legal

Daniel Sanders fa5ab1c856 [mips][msa] Added support for matching addv from normal IR (i.e. not intrinsics)
The corresponding intrinsic is now lowered into equivalent IR (ISD::ADD) before instruction selection.

Daniel Sanders cb2929c239 [mips][msa] Corrected the definition of the dotp_[su].[hwd] intrinsics
The elements of the operands should be half the width of the elements of
the result.

Daniel Sanders f561730af8 [mips][msa] Removed unsupported dot product instructions (dotp_[su].b)
The dotp_[su].b instructions never existed in any revision of the MSA spec.

Daniel Sanders ce09d07824 [mips][msa] Added bnz.df, bnz.v, bz.df, and bz.v
These intrinsics are legalized to V(ALL|ANY)_(NON)?ZERO nodes,
are matched as SN?Z_[BHWDV]_PSEUDO pseudo's, and emitted as
a branch/mov sequence to evaluate to 0 or 1.

Note: The resulting code is sub-optimal since it doesnt seem to be possible
to feed the result of an intrinsic directly into a brcond. At the moment
it uses (SETCC (VALL_ZERO $ws), 0, SETEQ) and similar which unnecessarily
evaluates the boolean twice.

Daniel Sanders e6ed5b72f1 [mips][msa] Added load/store intrinsics.

Daniel Sanders f9aa1d1902 [mips][msa] Added cfcmsa, and ctcmsa
The MSA control registers have been added as reserved registers,
and are only used via ISD::Copy(To|From)Reg. The intrinsics are lowered
into these nodes.

Daniel Sanders c426754a57 [mips][msa] Added tests for and.v, bmnz.v, bmz.v, bsel.v, nor.v, or.v, xor.v when non-byte vectors are used.
Note that all of these tests use ld.b and st.b for the loads and stores
regardless of the data size. This is because the definition of bitcast is
equivalent to a store/load sequence and DAG combiner accordingly folds bitcasts
to/from v16i8 into the load/store nodes to product load/store nodes with
type v16i8.
