gcse after reload removes the load imaginary part of the return value
(__complex__ float is returned in %eax/%edx pair):

This is probably a DF and/or target issue. The testcase can be simplified
to only call for example the first check_complex function in main().
It also fails with -O -fno-inline -fgcse-after-reload, mycacoshf is the
function that is miscompiled (as it returns a complex).
