[PATCH v4 08/18] perf clang jit: add PerfModule::doJIT to JIT perfhook functions

PerfModule::doJIT JIT compile perfhook functions and saves result into a map. Add a test case for it. At this stage perfhook functions can do no useful things because they can't invoke external functions and can't return value. Following commits are going to make improvment. Don't hook functions
