rs6000: Fix PR67344

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.

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.

Remove index from AARCH64_FUSION_PAIR

    Instead of doing an explict index in aarch64-fusion-pairs.def, we
    should have an enum which does the index instead.  This allows
    you to add/remove them without worrying about the order being
    correct and having holes or worry about merge conficts.

    OK? Bootstrapped and tested on aarch64-linux-gnu with no regressions.

    ChangeLog:
    * aarch64-fusion-pairs.def: Remove all index to AARCH64_FUSION_PAIR.
    * config/aarch64/aarch64-protos.h (aarch64_fusion_pairs_index): New enum.
    (aarch64_fusion_pairs): Base the shifted value on the index instead
    Rewrite AARCH64_FUSE_ALL to be based on the end index.
    of the argument to AARCH64_FUSION_PAIR.
    * config/aarch64/aarch64.c: Remove the last argument to AARCH64_FUSION_PAIR.
