Fix off-by-one error in PPCaching.cpp token annotation assertion

This assert is intended to defend against backtracking into the middle
of a sequence of tokens that is being replaced with an annotation, but
it's OK if we backtrack to the exact position of the start of the
annotation sequence. Use a <= comparison instead of <.

Fixes PR25946
