[ARM] Add some missing thumb1 opcodes to enable peephole optimisation of CMPs

This adds a number of missing Thumb1 opcodes so that the peephole optimiser can
remove redundant CMP instructions.

Reapplying this after the first attempt broke non-thumb1 code as the t2ADDri
instruction can be used with frame indices. In thumb1 we use tADDframe.
