Currently the handling of include translation is confusing to read,
using a tri-state integer without much clarity on what different states
mean. This patch cleans this up to use explicit enumerators indicating
the different possible states instead, and fixes a bug where the option
'-flang-info-include-translate' ended being accidentally unusable.
PR c++/110980
