a813f5996e Fix converting types for UNION queries (may produce LOGICAL_ERROR) 
CI founds [1]:

    2022.02.20 15:14:23.969247 [ 492 ] {} <Fatal> BaseDaemon: (version 22.3.1.1, build id: 6082C357CFA6FF99) (from thread 472) (query_id: a5187ff9-962a-4e7c-86f6-8d48850a47d6) (query: SELECT 0., round(avgWeighted(x, y)) FROM (SELECT toDate(toDate('214748364.8', '-922337203.6854775808', '-0.1', NULL) - NULL, 10.000100135803223, '-2147483647'), 255 AS x, -2147483647 AS y UNION ALL SELECT y, NULL AS x, 2147483646 AS y)) Received signal Aborted (6)

The problem is that subqueries returns different headers:
- first query  -- x, y
- second query -- y, x

v2: Make order of columns strict only for UNION

Fix special case of trivial regexp 
Previously, we would alsays set 1 in case of a trivial regex (which is
correct). If someone in future builds a negated operator, then this
will produce wrong results. Right now, negation of regexp (SQL: NOT
MATCH) is implemented at a higher level, so we are safe and this is more
a preventive fix.

Pass strings in some places as string_view 
The original goal was to get change

  const auto & needle = String(
        reinterpret_cast<const char *>(cur_needle_data),
        cur_needle_length);

in Functions/MatchImpl.h into a std::string_view to save an allocation +
copy. The needle is eventually passed as search pattern into the re2
library. Re2 has an alternative constructor taking a const char * i.e. a
NULL-terminated string. Here, the needle is NULL-terminated but
1. this is only because it is passed inside a ColumnString yet this is
   not always the case (e.g. fixed string columns has a dense layout w/o
   NULL terminator).
2. assuming NULL termination for users != MatchImpl of the regex code is
   too dangerous.

So, for now we'll stay with copying to be on the safe side. One fine day
when re2 has a ptr/size ctor, we can use std::string_view.

Just changing a few other places from std::string to std::string_view
but this will not help with performance.

Refactoring: Make template instantiation easier to read 
- introduced class MatchTraits with enums that replace bool template
  parameters

- (minor: made negation the last template parameters because negation
  executes last during evaluation)
