compiler/mode_errors.m:
When more than half of the branches in a disjunction ground a variable,
but some branches leave it non-ground, the error is almost certainly
in the branches that leave the variable non-ground. Therefore users
are very likely to find the ground insts we print for the branches
that ground the variable to be just clutter.
Change things so that by default, we print the inst of the variable
only for the branches that leave it non-ground. (We still print its inst
in all branches with verbose errors.)
To make the messages processable by the error utility, in the message
about the inst of the variable in a branch, print the context of the
branch in the usual context position, not in the body of the message.
compiler/error_util.m:
Allow for the fact that we can now generate an empty list of messages
for a branch in the non-verbose-errors case.
