Replace the use of the internal_report structure (for reports from
engines, MPV etc) with the Rose program interpreter.
SOM processing was reworked to use a new som_operation structure that is
embedded in the appropriate instructions.
Previously, the exhaustion vector was a standard bitvector, which
required an expensive memset() call at init for databases with a large
number of exhaustion keys.
Unifies all literal match paths so that the Rose program is used for all
of them. This removes the previous specialised "direct report" and
"multi direct report" paths. Some additional REPORT instruction work was
necessary for this.
Reworked literal construction path at compile time in prep for using
program offsets as literal IDs.
Completely removed the anchored log runtime, which is no longer worth
the extra complexity.
Move report preconditions (bounds, exhaustion, etc) into program
instructions and use a more direct path to the user match callback than
the adaptor functions.
Report handling has been moved to new file src/report.h. Reporting from
EOD now uses the same instructions as normal report handling, rather
than its own.
Jump target tracking in rose_build_bytecode.cpp has been cleaned up.
Remove the RoseEngine and stream state pointers frose RoseContext, as
they are also present in core_info.
Unify stream state handing in Rose to always use a char * (we were often
a u8 * for no particularly good reason) and tidy up.
Replace the RoseLiteral structure with more program instructions; now,
instead of each literal ID leading to a RoseLiteral, it simply has a
program to run (and a delay rebuild program).
This commit also makes some other improvements:
* CHECK_STATE instruction, for use instead of a sparse iterator over a
single element.
* Elide some checks (CHECK_LIT_EARLY, ANCHORED_DELAY, etc) when not
needed.
* Flatten PUSH_DELAYED behaviour to one instruction per delayed
literal, rather than the mask/index-list approach used before.
* Simple program cache at compile time for deduplication.
- cleanups
- add sparse iter instructions
- merge "root" and "sparse iter" programs together
- move program execution to new file program_runtime.h
- simplify EOD execution
