Zlatko Buljan 48f1f39bfe Revert r254897 "[mips][microMIPS] Implement LH, LHE, LHU and LHUE instructions" 
Commited patch was intended to implement LH, LHE, LHU and LHUE instructions.
After commit test-suite failed with error message in the form of:
fatal error: error in backend: Cannot select: t124: i32,ch = load<LD2[%d](tbaa=<0x94acc48>), sext from i16> t0, t2, undef:i32
For that reason I decided to revert commit r254897 and make new patch which besides implementation and standard regression tests will also have dedicated tests (CodeGen) for the above error.

Daniel Sanders ea4f653d18 [mips][ias] Range check uimm2 operands and fix a bug this revealed. 
Summary:
The bug was that the MIPS32R6/MIPS64R6/microMIPS32R6 versions of LSA and DLSA
(unlike the MSA version) failed to account for the off-by-one encoding of the
immediate. The range is actually 1..4 rather than 0..3.

Daniel Sanders 0f596814e9 [mips][msa] Remove copy_u.d and move copy_u.w to MSA64. 
Summary:
The forwards compatibility strategy employed by MIPS is to consider registers
to be infinitely sign-extended. Then on ISA's with a wider register, the result
of existing instructions are sign-extended to register width and zero-extended
counterparts are added. copy_u.w on MSA32 and copy_u.w on MSA64 violate this
strategy and we have therefore corrected the MSA specs to fix this.

We still keep track of sign/zero-extension during legalization but we now
match copy_s.[wd] where required.

No change required to clang since __builtin_msa_copy_u_[wd] will map to
copy_s.[wd] where appropriate for the target.
