Don't force SP-relative addressing for statepoints
Summary:
... when the offset is not statically known.
Prioritize addresses relative to the stack pointer in the stackmap, but
fallback gracefully to other modes of addressing if the offset to the
stack pointer is not a known constant.
Patch by Oscar Blumberg!
