Many safepoint tables do not contain any deoptimization info and/or no
callee-saved registers. Do not emit empty fields for all entries in this
case.
This often shrinks the size of the encoded safepoint table by more than
50%.
Drive-by cleanups:
- Rename fields of the safepoint table entries to clarify their meaning
("tagged slots" instead of "bits", "tagged register indexes" instead of
"register bits").
- Include the PC in the decoded {SafepointEntry} to make it the single
source of truth.
