cmd/compile: fix contrived line number errors If a general comment contains multiple newline characters, we can't simply unread one and then re-lex it via the general whitespace lexing phase, because then we'll reset lineno to the line before the "*/" marker, rather than keeping it where we found the "/*" marker. Also, for processing imports, call importfile before advancing the lexer with p.next(), so that lineno reflects the line where we found the import path, and not the token afterwards. Fixes #14520.

cmd/compile/internal/syntax: differentiate between ';' and '\n' in syntax errors Towards better syntax error messages: With this change, the parser knows whether a semicolon was an actual ';' in the source, or whether it was an automatically inserted semicolon as result of a '\n' or EOF. Using this information in error messages makes them more understandable. For #17328.
