This patch flattens regset.h. it only includes bitmap.h which will come
from backend.h and hard-reg-set.h which is going to be included by
rtl.h. The vast majority of files which include regset already include
rtl.h, so its almost never needed.
This patch shows the result on all files in a virgin state (ie, as if no
other patch has been applied) note sel-sched-ir.h and df.h both include
regset.h.. its flattened into them as well, but will later come out when
those 2 are flattened.
bootstraps from scratch on x86_64-unknown-linux-gnu with no new
regressions. Also compiles all the files in config-list.mk.
* regset.h: Remove bitmap.h and hard-reg-set.h #includes.
* sel-sched-ir.h: Adjust includes.
* df.h: Likewise.
* dse.c: Likewise.
* cgraphunit.c: Likewise.
