variable.c: avoid redundant iv scan in mrb_mod_cv_set().

Now `iv_get()` returns `pos+1` if it finds the entry, so you don't need
to call `iv_put()`. You can replace the entry value by assigning to
`t->ptr[pos-1]`.

variable.c: reduce memory usage of instance variable table

This is a fundamentally simplified reimplementation of #5317
by @shuujii
Instead of having array of `struct iv_elem`, we have sequences of keys
and values packed in single chunk of malloc'ed memory. We don't have to
worry about gaps from alignment, especially on 64 bit architecture,
where `sizeof(struct iv_elem)` probably consumes 16 bytes, but
`sizeof(mrb_sym)+sizeof(mrb_value)` is 12 bytes.
In addition, this change could improve memory access locality.
close #5317

Minimize the changes in #5277
...
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
