	cleaned up miscellaneous FTYPE proclamation stuff..
	..I changed my mind: PROCLAIM-AS-FUN-NAME is appropriate
		in PROCLAIM INLINE and PROCLAIM NOTINLINE after all.
	..got rid of separate PROCLAIM-AS-DEFSTRUCT-FUN-NAME in
		favor of ordinary PROCLAIM FTYPE
	..moved remove-from-*FREE-FUNCTIONS* logic from
		%COMPILER-DEFSTRUCT to PROCLAIM-AS-FUN-NAME
	..PROCLAIM-AS-FUN-NAME doesn't need to return NAME. Nor
		CHECK-FUN-NAME neither.
	..When %COMPILER-DEFSTRUCT sets the inline expansions of
		slot functions, it should proclaim their ftype too.
	Now that %COMPILER-DEFSTRUCT wants SB!XC:PROCLAIM, I
		rearranged things to make SB!XC:PROCLAIM available
		sooner, moving src/compiler/proclaim, and the
		src/compiler/knownfun that it depends on, earlier
		in stems-and-flags
