libphobos: Give _Unwind_Exception an alignment that best resembles
__attribute__((aligned))
in particular
+else version (X86) private enum __aligned__ = 16;
I don't yet see where/how struct _Unwind_Execption is allocated to
guarantee that alignment. Depending on the answer PR libstdc++/77691
(32-bit Solaris/x86 malloc only returns 8-byte aligned memory) or the
fact that the stack is only 4-byte aligned following the i386 psABI) may
be relevant.
