compiler-rt: bug in double_precision rep_clz

Hello,

I needed to apply the attached little patch rep_clz to get __adddf3
working on 32Bit x86 Linux.

__adddf3 doesn't seem to be part of the Library on any currently
supported Platforms. But if support for plattforms without FPU
should be added this probably is the correct version.
