LLVM can do everything that you want: store code, jit compile it, etc. 
What it can't do is provide portability for C code.  C is not a portable 
language: target-specific details like the size of datatypes leak into the 
generated code, preprocessor symbols are defined differently for different 
targets, etc.

If you use a portable input language, LLVM can preserve that portability. 
However, for C, you can't be guaranteed that your input will be portable.
