+PowerPC mishandles xscmpudp instruction
+Description of problem:
+xscmpudp instruction is mishandled
+Steps to reproduce:
+1. Compile the attached program with VSX (e.g. `RUSTFLAGS=-Ctarget-feature=+vsx cargo build --target=powerpc64-unknown-linux-gnu`)
+2. Run the program and expect assertions to pass.
+3. See assertions fail.
+Additional information:
+When VSX is disabled, the `fcmpu` instruction is emitted instead (and handled properly).  See the offending program:
+```
+pub fn main() {
+    use std::hint::black_box;
+    assert!(black_box(f64::NAN)
+        .clamp(black_box(0f64), black_box(0f64))
+        .is_nan());
+}
+```
