For me its 220 vs. 233 seconds which is totally acceptable.  Another way
would be to bump the required Emacs version to 25.1 where we could omit
all (f)boundp-checks.  Or as a third option, we could only check

  (fboundp 'prettify-symbols-default-compose-p)

which is always defined (even directly after emacs -Q) and available
from 25.1 on where we can assume that prettify-symbols-compose-predicate
and tex--prettify-symbols-alist are also available.  And then we can
defer loading tex-mode in VirTeX-common-initialization.
