[LLVMdev] how to set -pre-ra-sched from code?

I've found that I need to set the -pre-RA-sched parameter when using
tools like llc to get the kind of instruction scheduling I want.
However I'm normally generating and running code on the fly using the
JIT, and can't figure out how to set the -pre-RA-sched option anywhere
other than on the command line for the provided tools. So what code
would I write (or where is the API?) to change the pre-regalloc
instruction scheduler algorithm?
I've been unable to find this in the documentation or reading source
code; a pointer would be really useful.
