* Fixed bug in Thumb2 pop caused by me incorrectly assuming that
  ARM_SP == 13, ARM_LR == 14, and ARM_PC == 15, which is not the case
* updated CMakeLists to include building arm regression test
* added explicit casts for 64 bit visual studio 2012 build to get around
  truncation warnings from size_t conversion
