Specify the type of scop->region

Changing the type of scop::region from void* to sese, as this is
the only type assigned to scop::region for now. No functional changes intended.
Passes regtest and bootstrap.

Missing parts of fixes for in-tree libiconv

(The previous iconv-related commit missed the config/iconv.m4 change.)

Original description:

This is the second in a series of patches to make a build with an
in-tree GNU libiconv work as designed.

Currently GDB is the only toolchain component which actually uses an
in-tree libiconv.  This patch modifies the common AM_ICONV to use an
in-tree libiconv when present and not already provided by libc.
(GDB's workaround uses an in-tree libiconv even when libc provides
iconv(3); I'm not sure when or why that would be desirable.)

config/ChangeLog:
2015-08-24  Yaakov Selkowitz  <yselkowi@redhat.com>

* iconv.m4 (AM_ICONV_LINK): Use in-tree libiconv when present.
