      sim/common: convert sim-arange to use sim-inline

broke many simulator targets.  I fixed aarch64 in a previous commit
without realising how many other target were also broken.

This commit adds the missing includes (sim-assert.h and libiberty.h),
which seem to be needed by many simulator targets, in a central
location, this should fix most builds.

sim/common/ChangeLog:

	* sim-base.h: Add 'sim-assert.h' include.
	* sim-basics.h: Add 'libiberty.h' include.
