Recognize __builtin_isinf and BI__builtin_isfinite (and a few other builtin opcodes for finite checks) in testFPKind().

TDC can check for infinity, and for finite with an inversion of the result.

'finite', '__finite', ... seemed to always work as double with extension/trunction from float/long double. I would guess it is expected to handle those as well with TDC, or?
