It is allocated when .elc file is loaded. Each compiled `dolist'
contains the uninterned symbol #:--cl-dolist-temp--, and its name is
allocated through the following path:
lread.c:read1
2780 Lisp_Object result = uninterned_symbol ? make_symbol (read_buffer)
2781 : intern (read_buffer);
lread.c:make_symbol
3294 return Fmake_symbol ((!NILP (Vpurify_flag)
3295 ? make_pure_string (str, len, len, 0)
3296 : make_string (str, len)));
alloc.c:make_pure_string
4787 s = (struct Lisp_String *) pure_alloc (sizeof *s, Lisp_String);
4788 s->data = (unsigned char *) pure_alloc (nbytes + 1, -1);
