[Bug target/30980] [4.3 Regression] Recent complex miscompilation

[dominiq at lps dot ens dot fr]

Note that the drawback of the optimization replacing sin+cos by cexpi on PPC
Darwin has been dissected in PR31249.

In comment #16, I proposed a patch. Before applying it, it would be nice to
test if the other platforms affected by this bug are also affected by the bad
optimization and if the patch does not cause timing regressions on platforms
for which the optimization is working (mostly Linux).
