533d177a98 Fix correct reset value for ARM CP15 c1 auxiliary control register
According to ARM Cortex A8 Technical Reference Manual, the reset value for CP15 c1 auxiliary control
register is 2, not zero (page 3.12).

eca1bdf415 Log reset events (Jan Kiszka)
Original idea&code by Kevin Wolf, split-up in two patches and added more
archs.

This patch introduces a flag to log CPU resets. Useful for tracing
unexpected resets (such as those triggered by x86 triple faults).

a87aa10b85 ARMv6: fix SIMD add/sub carry flags (Vincent Palatin).
After a quick code review, it seems to be a bad cut-n-paste between
16-bit and 8-bit UADD/USUB, indeed UADD8/USUB8 tries to set GE bits by
pair instead of one at a time.
Besides, the addition operations (UADD8/UADD16) set GE bits to "NOT
carry" instead of "carry" (probably once again due to a copy of the
substraction code which sets flags to "NOT borrow")

op_helper.c

translate.c
 - gen_smul_dual should sign-extend from 16 bit to 32 bit and not from
   8 to 32
 - disas_arm_insn:
   * smlalxy:  that was completely wrong;  now the addition is
     performed as for smlald
   * pkhtb:  optional ASR not taken into account (similar
