--- Comment #3 from keremkat+llvm at gmail.com ---
Target lowering converts @llvm.powi.f64 builtin to a call to the function
__powidf2 which is defined in libgcc2 and compiler-rt. JIT on windows resolves
address of __powidf2 to 0x0 as it cannot find the symbol. callq 0 is trapping

The culprit in this case is lack of linking of the compiler-rt library into
lli.exe. (tested on Win8 x86-64)
