"*ior<mode>_mask" is a define_insn_and_split, so it shouldn't use
can_create_pseudo in its instruction condition, because IRA can then
create such an instruction, and the condition becomes false before
the insn is split. Use a scratch instead.

The "*and<mode>3_imm_dot_shifted" pattern is a define_insn_and_split,
like most "dot" patterns: if its output is not assigned cr0 but some
other cr reg, it splits to a non-dot insn and a compare.
Unfortunately that non-dot insn will clobber cr0 as well. We could
add another clobber (with "=X,x"), but then that second alternative
is never useful; instead, just remove that second alternative.

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.

(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.)

2015-08-24 Yaakov Selkowitz <yselkowi@redhat.com>
* iconv.m4 (AM_ICONV_LINK): Use in-tree libiconv when present.
