(convert_and_check, overflow_warning, unsigned_conversion_warning):
New functions.  Prototypes added to c-tree.h.

(finish_decl, grokdeclarator, finish_struct): Report
overflows in storage sizes.

(lshift_double): Don't report arithmetic overflow, since the
C standard doesn't seem to require it here.
(force_fit_type): Accept new parameter specifying whether a signed
overflow has already occurred.  Yield overflow indication.
All callers changed.

	(cmpXf insns): Allow 0.0 for either operand of the
	comparison.  Update output template to handle 0.0 as one
	of the operands.
	(movsi insn, fp->fp case): Update constraints and template to
