1. The arch directive now appears before the cpu directive
2. Long run lines were split across multiple lines
    
No functional changes.

4faa2b38fb [mips][msa] Fix issue with immediate fields of LD/ST instructions
not being correctly encoded/decoded.
In more detail, immediate fields of LD/ST instructions should be
divided/multiplied by the size of the data format before encoding and
after decoding, respectively.

The immediate field should be encoded as "imm - 1" as the CPU always adds one to that field.

006cff8d7b [mips][msa] Direct Object Emission support for CTCMSA and CFCMSA.
These instructions are logically related as they allow read/write of MSA control registers.
Currently MSA control registers are emitted by number but hopefully that will change as soon 
as GAS starts accepting them by name as that would make the assembly easier to read.

45ecbfc8e5 [mips][msa] Direct Object Emission of INSERT.{B,H,W} instruction.
INSERT is the first type of MSA instruction that requires a change to the way
MSA registers are parsed. This happens because MSA registers may be suffixed by
an index in the form of an immediate or a general purpose register. The changes
to parseMSARegs reflect that requirement.

42d9ca6299 [mips][msa] Direct Object Emission support for the MSA instruction set.
In more detail, this patch adds the ability to parse, encode and decode MSA registers ($w0-$w31). The format of 2RF instructions (MipsMSAInstrFormat.td) was updated so that we could attach a test case to this patch i.e., the test case parses, encodes and decodes 2 MSA instructions. Following patches will add the remainder of the instructions.

Note that DecodeMSA128BRegisterClass is missing from MipsDisassembler.td because it's not yet required at this stage and having it would cause a compiler warning (unused function).
