feat(diagnostics): print source diagnostics in gcc file:line: layout
Lexer, parser, driver and codegen diagnostics now read
"<path>:<line>: error: <message>" instead of "error: <message> at line N
in <path>". The path is always printed as given on the command line.
Call sites pass the bare message to cps::sourceError/sourceWarning, which
carry printf format checking; reportError routes through the same helper.
The suite iii harness parses the new layout and matches the reason
against the message only. iii/template-class-pack-field passed only
because its reason regex matched the case path, so it is now
case-insensitive.

Failed source compilation does not write output; failed native linking does not replace an existing output file. Successful compilation overwrites an existing output file, but an output path that refers to any input source file (including a symbolic or hard link) is rejected. Runtime diagnostics of the compiled program (for example `[Fatal] line N: ...` and `Unhandled exception. Program terminated.`) are also written to stderr, so `OUTPUT` text alone appears on stdout. Missing input, including invoking `cpsc` without arguments, reports `cpsc: fatal error: no input files`. Ordinary lexical, syntax and semantic errors use `error:`; failures that prevent compilation, such as file I/O errors, use `fatal error:`. Compilation and argument failures end with one `compilation terminated.` line. Execution-stage failures do not print that line. |
