fix pointer dereference after realloc
...
In src/vm.c: mrb_funcall_with_block
stack_extend may realloc mrb->c->stbase, if argv points on mruby's stack,
then it points invalid address after stack_extend.
e.g. src/class.c: mrb_instance_new
This code:
```ruby
class A
def initialize(a0,a1,a2,a3,a4)
a0.is_a? Array
end
end
def f(a0,a1,a2,a3,a4)
A.new(a0,a1,a2,a3,a4)
f(a0,a1,a2,a3,a4)
end
f(0,1,2,3,4)
```
is expected to get exception
```
stack level too deep. (limit=(0x40000 - 128)) (SystemStackError)
```
but get segfault.

Fix ensure with yield context on break and return
...
How to reproduce:
class A
def x
yield
ensure
y
end
def y
end
end
# Work
A.new.x do
end
# Not work
# trace:
# [2] /tmp/a.rb:5:in A.x
# [0] /tmp/a.rb:15
# /tmp/a.rb:5: undefined method 'y' for main (NoMethodError)
A.new.x do
break
end
# trace:
# [2] /tmp/a.rb:5:in A.call
# [0] /tmp/a.rb:19
# /tmp/a.rb:5: undefined method 'y' for main (NoMethodError)
lambda do
A.new.x do
return
end
end.call
`self` in ensure is broken when yield and break/return are used.

Fix an error when calling a method implemented in C by super() with arguments. This fix makes the following code workable:
...
Expected:
class MRBTime < Time; def self.new; super(2012, 4, 21); end; end
MRBTime.new # => Sat Apr 21 00:00:00 2012
Actual:
class MRBTime < Time; def self.new; super(2012, 4, 21); end; end
MRBTime.new # => can't convert nil into Integer (TypeError)
