target/arm: Clear CPSR.IL and CPSR.J on 32-bit exception entry
On 32-bit exception entry, CPSR.J must always be set to 0
(see v7A Arm ARM DDI0406C.c B1.8.5). CPSR.IL must also
be cleared on 32-bit exception entry (see v8A Arm ARM
DDI0487C.a G1.10).
Clear these bits. (This fixes a bug which will never be noticed
by non-buggy guests.)
