[ELF2] - Implemented PT_GNU_STACK support, -z execstack option. PT_GNU_STACK is a entry in the elf file format which contains the access rights (read, write, execute) of the stack, it is always generated now. By default stack is not executable in this implementation. -z execstack can be used to make executable. Differential revision: http://reviews.llvm.org/D14571 llvm-svn: 253145

ELF: Omit PT_GNU_STACK segment if -z execstack is provided. In the previous patch (r254003), I made the linker emit PT_GNU_STACK unconditionally. But sometimes you want to have a control over the presence of the segment. With this patch, you can omit the segment by passing -z execstack option. llvm-svn: 254039

Always add PT_GNU_STACK. If -z stack-size is given, we need to add PT_GNU_STACK even if -z execstack is not given. llvm-svn: 295945
