Tamas Berghammer be379e1590 Revert "Use BKPT instead of UDF for arm/thumb breakpoints" ...

This reverts commit 293c18e067d663e0fe93e6f3d800c2a4bfada2b0.

The BKPT instruction generates SIGBUS instead of SIGTRAP in the Linux
kernel on Nexus 6 - 5.1.1 (kernel version 3.10.40). Revert the CL
until we can figure out how can we hanble the SIGBUS or how to get
back a SIGTRAP using the BKPT instruction.
