[release-branch.go1.20] go/scanner: reject large line and column numbers in //line directives Setting a large line or column number using a //line directive can cause integer overflow even in small source files. Limit line and column numbers in //line directives to 2^30-1, which is small enough to avoid int32 overflow on all reasonbly-sized files.
