Add initial nativecomp typeset and range propagation support

Add initial nativecomp typeset and range propagation support

This commit add an initial support for a better type propagation and
integer range propagation.

Each mvar can be now characterized by a set of types, a set of values
and an integral range.

	* lisp/emacs-lisp/comp.el (comp-known-ret-types): Store into
	typeset and remove fixnum.
	(comp-known-ret-ranges, comp-type-predicates): New variables.
	(comp-ctxt): Remove supertype-memoize slot and add
	union-typesets-mem.
	(comp-mvar): Remove const-vld, constant, type slots. Add typeset,
	valset, range slots.
	(comp-mvar-value-vld-p, comp-mvar-value, comp-mvar-fixnum-p)
	(comp-mvar-symbol-p, comp-mvar-cons-p)
	(comp-mvar-type-hint-match-p, comp-func-ret-typeset)
	(comp-func-ret-range): New functions.
	(make-comp-mvar, make-comp-ssa-mvar): Update logic.
	(comp--typeof-types): New variable.
	(comp-supertypes, comp-common-supertype): Logic update.
	(comp-subtype-p, comp-union-typesets, comp-range-1+)
	(comp-range-1-, comp-range-<, comp-range-union)
	(comp-range-intersection): New functions.
	(comp-fwprop-prologue, comp-mvar-propagate)
	(comp-function-foldable-p, comp-function-call-maybe-fold)
	(comp-fwprop-insn, comp-call-optim-func, comp-finalize-relocs):
	Logic update.

	* src/comp.c (emit_mvar_rval, emit_call_with_type_hint)
	(emit_call2_with_type_hint): Logic update.

	* lisp/emacs-lisp/cl-preloaded.el (cl--typeof-types): Undo the add
	of fixnum and bignum as unnecessary.

	* test/src/comp-tests.el
	(comp-tests-mentioned-p-1, comp-tests-cond-rw-checker-val)
	(comp-tests-cond-rw-checker-type, cond-rw-1, cond-rw-2)
	(cond-rw-3, cond-rw-4, cond-rw-5): Update for new type interface.
	(range-simple-union, range-simple-intersection): New integer range
	tests.
	(union-types): New union type test.
