When a function is declared and named with the blank identifier, only
the syntax is checked. This patch modifies the parser to add a dummy
node for each function declaration with a blank identifier name that
will be type checked like any function declaration.

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.

(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.
