Fix regression in embed() from pull-request ....

Fix regression in embed() from pull-request . With certain sets of arguments `compile_flags` might be left as `None`. This caused IPython to internally raise a TypeError when it tried to do a bitwise or between `shell.compile.flags` and `PyCF_ONLY_AST` in `CachingCompiler.ast_parse`. The regression was introduced in: b70ac12 embed(): Default to the future compile flags of the calling frame.
