New helper functions are created to handle data & prefetch aborts in AARCH32. They call platform functions, just like what report_exception is doing. As extended MSR/MRS instructions (to access lr_abt in monitor mode) are only available if CPU (Armv7) has virtualization extension, the functions branch to original report_exception handlers if this is not the case. Those new helpers are created mainly to distinguish data and prefetch aborts, as they both share the same mode. This adds 40 bytes of code.
