This patch fixes an lto profiledbootstrap failure with
-freorder-blocks-and-partition enabled. Currently compgotos
is the only pass that goes into cfglayout mode after bb reordering,
which is undesireable (and in the case of -freorder-blocks-and-partition
can cause illegal partitioning) because of the optimizations performed
on the cfg when going into cfglayout mode. Moved compgoto before
bb reordering to avoid these problems.
