limex: rework accept handling
...
Rather that iterating over NFAAccept structures and testing individual
bits in the state structure, iterate over the state vector and index
into accept structures.
Adds report list support to this path, unified with the report lists
used for exception handling.

Introduce a 64-bit LimEx model.
...
On 64-bit platforms, the Limex 64 model is implemented in normal GPRs.
On 32-bit platforms, however, 128-bit SSE registers are used for the
runtime implementation.

limex: implement variable shift NFA engines
...
Replaces the old LimEx NFA engines, which were specialised for model
size and number of shifts, with a new set of engines that can handle a
variable number of shifts.

Always init NFAContext::cached_br

LimEx NFA: no need to zero estate cache in STREAM

exception state in STREAM_FN and REV_STREAM_FN nowadays.
