This commit adds profiling support for powerpc64. Now we can do application
profiling and kernel profiling. To enable kernel profiling one has to build kgmon(8). I will enable the build once I managed to build and test powerpc (32-bit) kernels with profiling support. - add a powerpc64 PROF_PROLOGUE for _mcount. - add macros to avoid adding the PROF_PROLOGUE in certain assembly entries. - apply these macros where needed. - add size information to the MCOUNT function. MFC after: 3 weeks, together with r230291
