ruby: guard usage of GPUCoalescer code in Profiler
the GPUCoalescer code is used in the ruby profiler regardless of whether or not the coalescer code has been compiled, which can lead to link/run time errors. here we add #ifdefs to guard the usage of GPUCoalescer code. eventually we should refactor this code to use probe points.
