Message:
Committed patchset #1 manually as r17295.
Description:
Add tool to visualize machine code/lithium.
In the process:
- Add a command-line flag --opt-code-positions to track source position
information throughout optimized code.
- Add a subclass of the hydrogen graph builder to ensure that the source
position is properly set on the graph builder for all generated hydrogen
code.
- Overhaul handling of source positions in hydrogen to ensure they are
passed
through to generated code consistently and in most cases transparently.
