From: Luo <xionghu....@intel.com>
save the llvm bitcode to program->binary: insert a byte in front of the
bitcode stands for binary type(0 means GEN binary, 1 means COMPILED_OBJECT, 2
means LIBRARY);
load the binary to module by ParseIR.
create random directory to save compile header files.
use strncpy and strncat to replace strcpy and strcat.
v6: fix enqueue_copy_fill bug, use '\0' instead of 0 in the header.
v7 binary header format issue: fix test_load_program_from_bin bug of
standalone kernel generated by gbe_bin_generater.
