Replace a renaming in a third-party file with a #define

Browse Source 
Our use of the clock-cycle counter from FFTW involved a rename of its
type ticks to our type CycleCounterTicks. This unnaturally bulks up
the diff from upstream, so undo it and use a simple #define to achieve
the same effect, as seen by our code.

/* To use the cycle counters in your code, simply #include "cycle.h" (this
file), and then use the functions/macros:
CycleCounterTicks getticks(void);
ticks getticks(void);
CycleCounterTicks is an opaque typedef defined below, representing the current time.
ticks is an opaque typedef defined below, representing the current time.
You extract the elapsed time between two calls to gettick() via:
double elapsed(CycleCounterTicks t1, CycleCounterTicks t0);
double elapsed(ticks t1, ticks t0);
which returns a double-precision variable in arbitrary units. You
are not expected to convert this into human units like seconds; it
