LLVM floating-point math intrinsics fail on s390x-unknown-linux-gnu

[gnzlbg]

On s390x-unknown-linux-gnu fails to compile due to errors in the following floating-point vector functions:

• abs
• cos
• fma
• sin
• sqrt

The errors are all of the form:

Intrinsic has incorrect return type!
void (<16 x float>*, <16 x float>*, <16 x float>*, <16 x float>*)* @llvm.fma.v16f32
LLVM ERROR: Broken function found, compilation aborted!

This is currently worked around by falling back to scalar code.
