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.
