performance for a particular set of patterns and corpus of data
to be scanned.

106667e24e refactor mcclellan runtime 
1. use u32 to hold the state during runtime to prevent repeated zero extension
2. have a tight small loop for processing characters which breaks when
   something interesting happens

5a842caaf1 shufti: slightly faster short shufti operation 
It is better to shift the high lane values in an XMM
before then using insert to combine the high and low lanes.

1a24b0b4db ng_equivalence: don't use ptr_vector 
Switch over ptr_vector<T> to vector<unique_ptr<T>>. This works around
some issues we were seeing with MSVC builds, where the contents of the
ptr_vector were being destroyed when it was returned.

8869dee643 rose: simplify long lit table, add bloom filter 
Replaces the original long lit hash table (used in streaming mode) with a
smaller, simpler linear probing approach. Adds a bloom filter in front
of it to reduce time spent on false positives.

Sizing of both the hash table and bloom filter are done based on max
load.

68bf473e2e fdr: move long literal handling into Rose 
Move the hash table used for long literal support in streaming mode from
FDR to Rose, and introduce new instructions CHECK_LONG_LIT and
CHECK_LONG_LIT_NOCASE for doing literal confirm for long literals.

This simplifies FDR confirm, and guarantees that HWLM matchers will only
be used for literals < 256 bytes long.

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.
