Add support for optimization reports.
Summary:
This patch adds a new flag -Rpass=. The flag indicates the name
of the optimization pass that should emit remarks stating when it
made a transformation to the code.
This implements the design I proposed in:
https://docs.google.com/document/d/1FYUatSjZZO-zmFBxjOiuOzAy9mhHA8hqdvklZv68WuQ/edit?usp=sharing
Other changes:
- Add DiagnosticIDs::isRemark(). Use it in printDiagnosticOptions to
print "-R" instead of "-W" in the diagnostic message.
- In BackendConsumer::OptimizationRemarkHandler, get a SourceLocation
object out of the file name, line and column number. Use that location
in the call to Diags.Report().
- When -Rpass is used without debug info a note is emitted alerting
the user that they need to use -gline-tables-only -gcolumn-info to
get this information.
