[PATCH 04/12] Remove #if HAVE_PYTHON

[Yao Qi <yao@codesourcery.com>]

This patch removes some unnecessary "#if HAVE_PYTHON" so that more
code is generalized.

gdb:

2014-02-14  Pedro Alves  <pedro@codesourcery.com>
	    Yao Qi  <yao@codesourcery.com>

	* varobj.c: Remove "#if HAVE_PYTHON" and "#endif".
	(varobj_get_iterator): Wrap up code for pretty-printer by
	"#if HAVE_PYTHON" and "#endif".
	(update_dynamic_varobj_children): Likewise.
