PATCH COMMITTED: Let gold build with gcc 4.3.0

[Ian Lance Taylor]

I committed this patch to let gold build with gcc 4.3.0.

There were two mildly interesting things.  First, gcc 4.3.0 found a
bug in gold using the array bounds check: x86_64.cc was using a 64-bit
swap where it should have been using a 32-bit swap.  Second, I had to
add a configure test for a bug in gcc 4.3.0, gcc bug 35546.
