Also loops with today's trunk. Without -mlra we get an immediate ICE instead:
lra-split-loop.c.c: In function 'f':
lra-split-loop.c.c:28:1: error: unable to find a register to spill in class
'DATA_REGS'
28 | }

lra-split-loop.c.c:28:1: error: this is the insn:
(jump_insn 27 26 28 2 (set (pc)

lra-split-loop.c.c:28: confused by earlier errors, bailing out
