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.
