Is it comparing the world to anything? No, so it's not a metaphor.

Synecdoche is when a specific part of something is used to refer to the whole, e.g. "my wheels" for "my car". It is usually understood as a specific kind of metonymy. A simple sentence that displays synecdoche, metaphor, and metonymy is: "Fifty keels ploughed the deep", where "keels" is the synecdoche, as it names the whole (the ship) after a particular part (of the ship); "ploughed" is the metaphor, as it substitutes the concept of ploughing a field for moving through the ocean; and "the deep" is the metonym, as "depth" is an attribute associated with the ocean.
A metaphor for something that spoils something else could be "a rotten apple in the bunch." This phrase suggests that a negative or harmful element within a group can negatively impact the whole.

No, Mother To Son by Langston Hughes does not have personification. However, the whole poem is basically a huge metaphor.
Firstly the whole image of sailing out on the tide is a metaphor for death. The bar is a metaphor for the boundary between this life and the next. The Pilot stands for God.
The poem itself is a metaphor. It doesn't have any specific ones in it. He is basically saying that the world is a miracle, which is a metaphor that covers the whole poem.
