Remove newlines between imports

[yousefmoazzam]

In several places such as the following:

c-compiler/src/parse/c.rs

Lines 1 to 4 in 3e75565

	use std::collections::VecDeque;
	use crate::lex::Token;
	use crate::parse::Identifier;

there are newlines between imports.

rustfmt will take care of ordering imports as long as there are no newlines separating them, so it's better to get rid of the newlines and let rustfmt take care of that.
