Even for pre-LRA with reload in GCC 4.7.0:
t.c: In function ‘f’:
t.c:91:1: note: unable to find a register to spill in class ‘GR_REGS’

Oh if we add back the s0 case, it fails at -O1 and above too.

On the trunk I get:
t.c: In function ‘f’:
t.c:94:1: error: s0 cannot be used in ‘asm’ here
94 | }
| ^
First with the RISCV example.
After removing the s0 variable usage I still get the ICE.
