compiler: Accept numeric literals with leading zeroes.

    When a numeric literal with leading zeroes was seen in the parser, it
    would only be accepted if it were a valid hex or octal literal.  Any
    invalid numeric literal would be split up into multiple tokens: the
    valid hex/octal literal followed by the rest of the characters.
    Instead, when scanning a numeric literal with leading zeroes, always
    accept the number and give an appropriate error if the accepted number
    does not fit in the expected base.

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.
