standalone version of fixunsxfdi() from libgcc2.c

Hi,

The 4.3.5 release fails to successfully compile libgcc. In particular the
fixunsxfdi() routine fails with an internal compiler error for -O1 & -O2. The
popcountdi2() routine fails with an internal compiler error for -Os.

This was tested using an x86 -> m68k cross compiler configured as such:

#!/bin/bash

set -x

optlevel="O1"
export CFLAGS="-${optlevel} -g -fomit-frame-pointer"

#        --enable-secureplt \
#        --enable-version-specific-runtime-libs \
#        --with-gxx-include-dir=<dirname> \
#        --enable-languages=all,obj-c++ \
#        --disable-debug \
BOOT_CFLAGS="$CFLAGS" \
    CFLAGS_FOR_TARGET="$CFLAGS" \
    LIBCFLAGS="$CFLAGS" \
    LIBCXXFLAGS="${CFLAGS} -fno-implicit-templates" \
    CXXFLAGS="$CFLAGS" \
    FCFLAGS="$CFLAGS" \
    CXXFLAGS_FOR_TARGET="$CFLAGS" \
    GCJFLAGS="$CFLAGS" \
    JCFLAGS="$CFLAGS" \
    GNATLIBCFLAGS="$CFLAGS" \
    ADA_CFLAGS="$CFLAGS" \
    ADAFLAGS="$CFLAGS" \
    `dirname ${0}`/configure \
        --prefix=/opt/cross/q700/gcc-4.3.5-${optlevel}-c,c++ \
        --target=m68k-netbsdelf1.6.1 \
        --with-sysroot=/opt/cross/q700 \
        --with-build-time-tools=/opt/cross/q700/binutils-2.16.1/bin \
        --enable-languages=c,c++ \
        --enable-__cxa_atexit \
        --enable-gather-detailed-mem-stats \
        --disable-libgomp \
        --with-system-zlib \
        --with-gmp=/opt/GMP-4.3.2 \
        --with-mpfr=/opt/MPFR-2.4.2 \
        --with-gnu-ld \
        --with-gnu-as

set +x

gcc-4.2.4 seems ok.
