This patch fixes up df.h. It contains 5 headers that will form part of
backend.has well as hard-reg-set.h which is now going to be included by
rtl.h.
The other 3 includes are required for df.h to compile, and it makes
sense to leave them here.
furthermore, resource.h, sched-int.h and valtrack.h all include df.h,
amongst other things, so flatten them as well. Now only source files
will include df.h and we can see if it may belong in some other
aggregator (or even become one) after include reduction.
All the requisite adjustments to source files will be in the final patch.
Bootstraps from scratch on x86_64-unknown-linux-gnu with no new
regressions. Also compiles all the files in config-list.mk.
* resource.h: Flatten hard-reg-set.h and df.h.
* sched-int.h: Flatten insn-arrt.h and df.h.
* valtrack.h: flatten bitmap.h, df.h, and rtl.h
* df.h: Flatten includes, leaving regset.h, alloc-pool.h and timevar.h.
