fbcb582942 [mips][msa] Added support for matching mulv, nlzc, sll, sra, srl, and subv from normal IR (i.e. not intrinsics)

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.

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.

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.

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.

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.

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.
