6e533589bb rose: move END instruction to start of enum 
Stop overloading END as the last Rose interpreter instruction, use new
sentinel LAST_ROSE_INSTRUCTION for that.

This change will also make it easier to add new instructions without
renumbering END and thus changing all generated bytecodes.

997787bd4b rose: add CHECK_SINGLE_LOOKAROUND instruction 
This specialisation is cheaper than the shufti-based variants, so we
prefer it for single character class tests.

13af3bfb74 rose: decouple build-time program representation 
This commit replaces the build-time representation of the Rose
interpreter programs, from a class containing a discriminated union of
the bytecode structures to a class hierarchy of build-time prototypes.

This makes it easier to reason about and manipulate Rose programs during
compilation.

f4fa6cd4dd rose: tighten up requirements for catch up 
We only need to catch up when there is an actual anchored table, not
merely when there are successors of anchored_root in the Rose graph.

ae14187462 rose: use min of max_offset in left merges 
Be more careful with max_offset, since we rely on it ofr ANCH history
cases. Also adds tighter assertions.

bfaa0acaea rose: preserve lit properties when building masks 
This fixes a bug with commit 6a6b0e5, which did not preserve the
requires_explode and requires_benefits properties when a new literal was
generated to add an HWLM and/cmp mask.

Also extends the requires_explode handling to allow masked literals.
