Avoid writing to purespace
* src/alloc.c (Fmake_string): Don't write to empty string contents.
(allocate_vector): Don't write to empty vector size.
* src/character.h (CHECK_CHARACTER_CAR, CHECK_CHARACTER_CDR):
Don't call unnecessary XSETCAR or XSETCDR.
* src/lisp.h (STRING_SET_UNIBYTE, STRING_SET_MULTIBYTE): Don't
write to empty string size_byte.
