[PATCH] D31331: [mips][msa] Truncation of vector elements for instructions creating ISD::SHL, ISD::SRL or ISD::SRA nodes

- Added classes covering patterns which remove and nodes for sll, srl and sra instructions in  `MipsMSAInstrInfo.td`
- Modified the existing patterns for bclr, bneg, bset instructions to match the additional and node which we now create
- Dropped changes in `test/CodeGen/Mips/msa/3r-s.ll`, since we do not generate and instructions now, so no changes required
- Added a test which specifically checks for said and instructions not being present in the resulting code
