add utest load_program_from_gen_bin.

this test case would check whether genProgramSerializeToBinary in
backend can generator gen binary correctly.

rename load_program_from_bin to load_program_from_bin_file.
the difference is load_program_from_bin_file could either load program
from llvm binary or gen binary file generated by gbe_bin_generator.
