  1. use correct svar 

    Without this patch, svar location is used "nearest Ruby frame".
It is almost correct but it doesn't correct when the `each` method
is written in Ruby.

```ruby
class C
  include Enumerable
  def each
    %w(bar baz).each{|e| yield e}
  end
end

C.new.grep(/(b.)/){|e| p [$1, e]}
```

This patch fix this issue by traversing ifunc's cfp.

Note that if cfp doesn't specify this Thread's cfp stack, reserved
svar location (`ec->root_svar`) is used.
