fe1479c3ad Implement (very) basic Thumb2-EE support. This doesn't actually implement
EE state, just the associated system coprocessor registers.  It is sufficient

4cc633c38b Patch holes in ARM translation (Laurent Desnogues).
- gen_set_CF_bit31:  use the right value to set carry flag
 - shifter_out_im:  remove a spurious semi-colon
 - add a break for VSHRN, VRSHRN, VQSHRN, VQRSHRN
   size 2 case
 - sbfx, ubfx are v6t2 instructions

The correct cps user mode behaviour is unclear so it's left out from the

a1d1bb3101 Refactor and enhance break/watchpoint API (Jan Kiszka)
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.

First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.

Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

bit 5 is fixed to 0 (bit 4 is the MSB of the mode), so the instruction mask

Besides, mmod flag is bit 17 (b14 is SBZ)
