If it was only a matter of error handling, then the best fix would
likely to be just avoiding __builtin_isinf if (clang AND i386 AND not
sse2).

The problem is that if we're relying on -fexcess-precision=standard
semantics in places besides infinity checks, then we won't get those
semantics on clang/i386/no-sse2 since it has no comparable option. (What
are we doing about compilers for x86-32 other than clang and gcc?)
