d: Fix regressing test failures on ix86-solaris2.11

The _Unwind_Exception struct had its alignment adjusted to 16-bytes,
however malloc() on Solaris X86 is not guaranteed to allocate memory
aligned to 16-bytes as well.

	PR d/102837

libphobos/ChangeLog:

	* libdruntime/gcc/deh.d (ExceptionHeader.free): Use memset to reset
	contents of internal EH storage.
