Are functions intrisically faster or easier for the intel comiler to optimize (e.g. inlining) as compared to subroutines?

No. If your function or subroutine is PURE, that can help.

PURE specifies that the procedure has no side effects. For a function, it also specifies that the arguments are not stored to.
