Renato Golin 6215f78195 Elide repeated register operand in Thumb1 instructions ... This patch makes the ARM backend transform 3 operand instructions such as 'adds/subs' to the 2 operand version of the same instruction if the first two register operands are the same. Example: 'adds r0, r0, #1' will is transformed to 'adds r0, #1'. Currently for some instructions such as 'adds' if you try to assemble 'adds r0, r0, #8' for thumb v6m the assembler would throw an error message because the immediate cannot be encoded using 3 bits. The backend should be smart enough to transform the instruction to 'adds r0, #8', which allows for larger immediate constants.
