Daniel Sanders 521e5ca5cc [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.
