Title: Better longdouble checks

Make checks for longdouble implementations more specific.
Also consider POWER7 when checking for double pair implementation.
Work round some odd float128 / complex256 behavior on PPC.
Disable use of float128 nifti data type unless we have a real binary128 data type.
