Ignore attempts to set the CPSR mode field to an invalid value. This is UNPREDICTABLE, but we should not cpu_abort() for things a malicious guest (or a confused user on the gdbstub interface) can provoke. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

Avoid using cpu_single_env in bank_number() -- if we were called via the gdb stub reading or writing the CPSR then it is NULL and we will segfault if we take the cpu_abort(). Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

The 1136r1 is actually a v6K core (unlike the 1136r0); mark it as such, thus enabling the TLS registers, NOP hints, CLREX, half and byte wide exclusive load/stores, etc. The VA-to-PA translation registers are not present on 1136r1, so introduce a new feature flag for them, which is enabled on 1176, 11MPCore and all v7 cores.

The Neon versions of int-float conversions must use the "standard FPSCR" rather than the default FPSCR. Implement this by having the helper functions take a pointer to the appropriate float_status value rather than simply taking a pointer to the entire CPUState, and making translate.c pass a pointer to vfp.fp_status or vfp.standard_fp_status appropriately for whether the instruction being translated is Neon or VFP.
