c-common.c, [...]: Delete code implementing -traditional mode.

	c-tree.h, c-typeck.c, cppexp.c, cpplex.c, cpplib.c, cpplib.h,

	builtin-types.def, builtins.def, dwarf2out.c, dwarfout.c,
	gcc.c, toplev.c: Delete code implementing -traditional mode.

	* ada/misc.c, ch/ch-tree.h, ch/decl.c, cp/decl2.c, f/com.c,
	f/lex.c, f/top.c, java/builtins.c, java/decl.c: Delete
	traditional-mode-related code copied from the C front end
	but not used, or used only to permit the compiler to link.

	* doc/bugreport.texi, doc/cpp.texi, doc/extend.texi,
	doc/invoke.texi, doc/standards.texi, doc/trouble.texi:
	Document removal of -traditional mode for compilation, and
	remove documentation only relevant to that mode.

	* config/nextstep.h, config/ptx4.h, config/svr4.h,
	config/convex/convex.h, config/d30v/d30v.h,
	config/i386/dgux.h, config/i386/osf1elf.h,

	config/sparc/sol2-sld-64.h, config/sparc/sol2.h,
	config/stormy16/stormy16.h: Remove all references to
	-traditional from target specs.  Delete all mention of the
	no-longer-necessary TRADITIONAL_RETURN_FLOAT macro.  Also
	delete a couple of commented-out definitions of
	DOLLARS_IN_IDENTIFIERS, with (incorrect) commentary referring
	to -traditional.

	* system.h: Poison TRADITIONAL_RETURN_FLOAT.
	* doc/tm.texi: Remove mention of TRADITIONAL_RETURN_FLOAT macro.

	* testsuite/gcc.c-torture/execute/920730-1t.c,
	testsuite/gcc.c-torture/execute/920730-1t.x,
	testsuite/gcc.dg/ext-glob.c: Delete test cases, only relevant
	to -traditional.
