compile.c: use %+PRIsVALUE instead of rb_inspect

* compile.c (get_exception_sym2type, iseq_build_from_ary_body):
  rely on %+PRIsVALUE instead of calling rb_inspect directly

This yields a minor size reduction on 32-bit x86:

   text	   data	    bss	    dec	    hex	filename
  96807	    772	     48	  97627	  17d5b	compile.o
  96851	    772	     48	  97671	  17d87	compile.orig
