Comment # 8 on bug 92709 from Nicolai Hähnle

Patch for LLVM

Here's a first cut at a patch that adds an llvm.ldexp.* intrinsic, so that
LibCallSimplifier generates that instead of the call to ldexpf, and codegen is
able to select the right instruction. With this change, Christoph's trace runs
to completion without errors.
