Print all errors (with line and column) when running analysis tests

[FnControlOption]

I find it useful to get all test failures at once

The changes to ErrorBuilder.zig should have test coverage. There are already some existing tests.

The error tracking in analysis_check.zig seems very useless. Why not just add something like this to end of the main function:

if (error_builder.hasMessages()) {
    return error.CheckFailed;
}
