d220e7f4fc Optimize the SIMD StringSearcher if needle_size is large 
This patch offers an additional optimization when the needle_size is
large. If the needle_size is larger than the haystack_size, there is
no need to search any more.

The optimized SIMD StringSearcher has led at most 41.7% than Volnitsky
algorithm when the needle_size is less than 21, and fallen behind only
about 1% even when the needle_size is bigger than 50, which is not
considered as a common case.

Test platform: ICX server
Test query: SELECT COUNT(*) FROM hits WHERE URL LIKE '%{Needle}%';

Needle_size	opt/baseline
5		141.7%
6		129.4%
8		118.5%
9		112.3%
10		107.4%
14		103.4%
20		100.2%
21		100.7%
51		99.0%

f5a6a86dec Optimize the SIMD StringSearcher by searching first two chars 
This patch offers the optimized SIMD StringSearcher by searching the first
and second chars together rather than only the first char, which will result
in big performance gain. The patch also provides a quick path when the needle
size is 1.

With this patch, I have tested the 43 queries in clickbench on ICX server.
Query 20 has got 35% performance gain. Other StringSearcher related queries
have got around 10% performance improvement. And the overall geomean of all
the queries has got 4.1% performance gain.

2ca47a6eb6 BackgroundSchedulePool should not have any query context 
BackgroundSchedulePool is used for some peridic jobs, not from the query
context, i.e. flush of Buffer table.

And for such jobs there cannot be any query context, and more
importantly it will not work correctly since that query_context will
eventually expires.

And this is the reason of this failures [1].
