* stabsread.c (define-symbol): Use invisible references

Browse source 
for TYPE_CODE_SET and TYPE_CODE_BITSTRING too.
	* eval.c (evaluate_subexp_standard):  When known, use the formal
	parameter type as the expected type when evaluating arg expressions.
	* ch-lang.c (evaluate_subexp_chill):  Likewise (for MULTI_SUBSCRIPT).
This (with a fix to gcc/config/sparc/sparc.h) fixes PR chill/8742.
