thopre added a parent revision: D60387: FileCheck [7/12]: Arbitrary long numeric expressions.

Processing of command-line definition of variable and logic around
implicit not directives both reuse parsing code that expects a line
number to be defined. So far, a special line number of 0 was used for
those users of the parsing code where a line number does not make sense.
This commit instead represents line numbers as Optional values so that
they can be None for those cases.
