Here is the full patch for mainline, bootstrapped (c,c++,objc,f77) and
checked on i686-pc-linux-gnu.  Very mechanical, in all.  I renamed the
head and end field to make sure no-one uses it again and gets away with
it unpunished...

OK for mainline?  Once it's there I'll do the same for tree-ssa.

        * basic-block.h (BLOCK_HEAD, BLOCK_END): Remove.
        (BLOCK_HEAD_TREE, BLOCK_END_TREE): Remove.
	(basic_block_def): Rename `head' to `head_' and `end' to `end_'.
        (BB_HEAD, BB_END): New accessor macros for the `head_' and `end_'
	fields of a basic block.
        * bb-reorder.c, bt-load.c, caller-save.c, cfg.c, cfganal.c,
	cfgbuild.c, cfgcleanup.c, cfglayout.c, cfgloop.c, cfgloopanal.c,
	cfgloopmanip.c, cfgrtl.c, combine.c, conflict.c, df.c, emit-rtl.c,
	final.c, flow.c, function.c, gcse.c, global.c, graph.c,
	haifa-sched.c, ifcvt.c, lcm.c, local-alloc.c, loop-unswitch.c,
	loop.c, postreload.c, predict.c, profile.c, ra-build.c, ra-debug.c,
	ra-rewrite.c, ra.c, recog.c, reg-stack.c, regclass.c, regmove.c,
	regrename.c, reload1.c, resource.c, sched-ebb.c, sched-rgn.c,
	sibcall.c, tracer.c, config/frv/frv.c, config/i386/i386.c,
	config/ia64/ia64.c: Use the BB_HEAD and BB_END macros instead of
	accessing the `head' and `end' fields of a basic block directly.
