Rustc has several test cases that ICE. Instead of removing them, they are marked as compile-fail so when they are fixed, CI will fail. This would then require you to mark it as build-pass/run-pass, ensuring that it doesn't regress in the future. In addition glacier has a big list of reported ICE's that are checked once a day to see if they are fixed yet. |

I could move this test to be part of the failure tests is actually not a bad idea. |

This adds implementation for the optabs for complex operations. With this the
following C code:
void g (float complex a[restrict N], float complex b[restrict N],
float complex c[restrict N])
{
for (int i=0; i < N; i++)
c[i] = a[i] * b[i];
}
generates
