Further improve redundant test/compare removal on the H8

gcc/
* config/h8300/logical.md (andqi3_1): Move BCLR case into define_insn_and_split.
Create length attribute on define_insn_and_split.  Only split for cases which we
know will use AND.
(andqi3_1<cczn>): Renamed from andqi3_1_clobber_flags.  Only handle AND here and
fix length computation.
(b<code><mode>msx): Combine QImode and HImode H8/SX patterns using iterator.
