calls.c, function.c: Always define PREFERRED_STACK_BOUNDARY if not already defined.

	* calls.c, function.c: Always define PREFERRED_STACK_BOUNDARY
	if not already defined.  Remove all #ifdefs on STACK_BOUNDARY;
	this macro is now required.

	* cselib.c (cselib_process_insn), flow.c (propagate_block),
	loop.c (find_and_verify_loops), reload.c (reload): Check
	for rtx code of CALL_INSN, not CALL, when deciding if we
	need to check for REG_SETJMP note.

	* gcse.c (compute_hash_table, compute_store_table): Update
	the #ifdef NON_SAVING_SETJMP code to the new REG_SETJMP
	logic.

	* config/avr/avr.c: Fix typo.
	* config/convex/convex.c (expand_movstr): Use adjust_address.
	* config/dsp16xx/dsp16xx.c: Define dsp16xx_compare_gen
	variable.
	* config/dsp16xx/dsp16xx.md: Correct calls to replace_equiv_address.
	* config/elxsi/elxsi.c: Include tree.h, expr.h, regs.h, and flags.h.
	Fix typo.
	* config/elxsi/elxsi.h: Don't define Rmode (typo for Pmode?)
	Do define STACK_BOUNDARY.
	* config/i370/i370.c: Include expr.h.
	* config/i860/sysv3.h, config/i860/sysv4.h, config/m32r/m32r.h,
	config/pa/som.h, config/v850/v850.h: Take in_ctors and
	in_dtors out of EXTRA_SECTIONS; take CTORS_SECTION_FUNCTION
	and DTORS_SECTION_FUNCTION out of EXTRA_SECTION_FUNCTIONS.
	* config/m88k/m88k.c: Include c-tree.h after expr.h.
	* config/pdp11/pdp11.c: Include expr.h and toplev.h.
	* config/romp/romp.c: Include expr.h after tree.h.
	Include toplev.h.
	(output_fpop): Use xmalloc, not oballoc.
	* config/we32k/we32k.c: Include expr.h.
