This patch adds runtime support for the Safe Stack protection to compiler-rt (see http://reviews.llvm.org/D6094 for the detailed description of the Safe Stack). This patch is our implementation of the safe stack on top of compiler-rt. The patch adds basic runtime support for the safe stack to compiler-rt that manages unsafe stack allocation/deallocation for each thread. Original patch by Volodymyr Kuznetsov and others at the Dependable Systems Lab at EPFL; updates and upstreaming by myself. Differential Revision: http://reviews.llvm.org/D6096 llvm-svn: 239763
