perf clang: Support compile IR to BPF object and add testcase
getBPFObjectFromModule() is introduced to compile LLVM IR(Module)
to BPF object. Add new testcase for it.
Test result:
$ ./buildperf/perf test -v clang
51: builtin clang support :
51.1: builtin clang compile C source to IR :
--- start ---
test child forked, pid 21822
test child finished with 0
---- end ----
builtin clang support subtest 0: Ok
51.2: builtin clang compile C source to ELF object :
--- start ---
test child forked, pid 21823
test child finished with 0
---- end ----
builtin clang support subtest 1: Ok
