llc lowers this to invalid asm.
Using Apple's system assembler:
ARM register expected -- `push
{d8,d9,d10,d11,d12,d13,d14,d15,r8,r10,r11,r4,r5,r6,r7,lr}
ARM register expected -- `pop
{d8,d9,d10,d11,d12,d13,d14,d15,r8,r10,r11,r4,r5,r6,r7,pc}
r167499 changes the clobber behavior of the Int_eh_sjlj_dispatchsetup pseudo-op
to clobber all registers and has uncovered that the D registers are not
properly being spilled when using SjLj on Thumb1.
