Further reduced test case
I've further reduced the test case as attached. The code is not miscompiled if
any of the following are true:
* -mcpu is not '970' (power5, power8, power9 all work)
* stack protector is not strong (-fno-stack-protector and -fstack-protector
work, -fstack-protector-strong fails)
* The union of floats is changed to a single float (`union { float x, r, s; };`
-> `float x;`)
* The mat4 ctor at line 98 is surrounded with #pragma GCC
optimize("no-stack-protector")
