@SjoerdMeijer,  @porglezomp - many thanks in advance, 
I'd like to clarify one aspect related to this diff- is it intentional that currently only pairs of cmp + bcc get fused (but e.g. not cmp + cbz or cmp + cbnz) (unless I'm missing something) 
and another question - after looking at https://github.com/gcc-mirror/gcc/blob/master/gcc/config/aarch64/aarch64.cc#L1326 - would it make sense to enable CmpBccFusion by default.
