T32: Implement ALU (shifted register) instructions (#3135)1.1.53
* T32: Implement ADC, ADD, AND, BIC, CMN, CMP, EOR, MOV, MVN, ORN, ORR, RSB, SBC, SUB, TEQ, TST (shifted register)
* OpCodeTable: Sort T32 list
* Tests: Rename RandomTestCase to PrecomputedThumbTestCase
* T32: Tests for AluRsImm instructions
* fix nit
* fix nit 2
