target/arm: Default handling of BTYPE during translation 
The branch target exception for guarded pages has high priority,
and only 8 instructions are valid for that case. Perform this
check before doing any other decode.

Clear BTYPE after all insns that neither set BTYPE nor exit via
exception (DISAS_NORETURN).

Not yet handled are insns that exit via DISAS_NORETURN for some
other reason, like direct branches.
