e0e42bf0bb Run the Thumb1 parser tests in Thumb2 mode, as well.
Thumb2 is a superset of Thumb1, so all of the encodings should still work.

0f3abd8d68 Tweak Thumb1 ADD encoding selection a bit.
When the destination register of an add immediate instruction is
explicitly specified, encoding T1 is preferred, else encoding T2 is
preferred.
