This change enables printing of relative column information if a prior line directive specified a valid column. If there was no line directive, or the line directive didn't specify a column (or the -C flag is specified), no column information is shown in file positions. Implementation: Column values (and line values, for that matter) that are zero are interpreted as "unknown". A line directive that doesn't specify a column records that as a zero column in the respective PosBase data structure. When computing relative columns, a relative value is zero of the base's column value is zero. When formatting a position, a zero column value is not printed. To make this work without special cases, the PosBase for a file is given a concrete (non-0:0) position 1:1 with the PosBase's line and column also being 1:1. In other words, at the position 1:1 of a file, it's relative positions are starting with 1:1 as one would expect. In the package syntax, this requires self-recursive PosBases for file bases, matching what cmd/internal/src.PosBase was already doing. In src.PosBase, file and inlining bases also need to be based at 1:1 to indicate "known" positions. This change completes the cmd/compiler part of the issue below. Fixes #22662.

README.md
The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
go run run.go
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgoand other Go tool chains.
