s390/fpu: remove anonymous union from struct fpu
The anonymous union within struct fpu contains a floating point register
array and a vector register array. Given that the vector register is always
present remove the floating point register array. For configurations
without vector registers save the floating point register contents within
their corresponding vector register location.
This allows to remove the union, and also to simplify ptrace and perf code.
