Peter Maydell 05d479a8c0 target/arm: For v8.1M, always clear R0-R3, R12, APSR, EPSR on exception entry 
In v8.0M, on exception entry the registers R0-R3, R12, APSR and EPSR
are zeroed for an exception taken to Non-secure state; for an
exception taken to Secure state they become UNKNOWN, and we chose to
leave them at their previous values.

In v8.1M the behaviour is specified more tightly and these registers
are always zeroed regardless of the security state that the exception
targets (see rule R_KPZV). Implement this.
