1. Remove the global reference to context. Currently we have: struct shiva_ctx *ctx_global defined as a global initialized variable in shiva.c. This global variable is predictable in the AARCH64 version because our Interpreter is an ET_EXEC (vs. PIE ET_DYN). This means that an attacker who's exploiting a memory corruption vulnerability could use this as leak to determine the ASLR space or gain access to other read/write primitives.
