(MD_FALLBACK_FRAME_STATE_FOR): Define.
Please do not create another definition of the register number for LR.
Earlier in the file it is defined as R_LR. Dropping in a completely
self-contained chunk with its own naming is confusing. LR_REGNO is
fine, but please define the necessary registers at the beginning of
the file and use them consistently throughout.
Okay with that cleanup.
Thanks, David
