IsTailPaddedMemberArray uses a FieldDecl's
getTypeSourceInfo() without checking for NULL.
FieldDecls may have NULL TypeSourceInfo, and in
fact some FieldDecls generated by Clang -- and
all FieldDecls generated by LLDB -- have no
TypeSourceInfo.
This patch makes IsTailPaddedMemberArray check
for NULL.
