Tom Lane d5b90cd648 Fix bogus handling of XQuery regex option flags. 
The SQL spec defers to XQuery to define what the option flags are
for LIKE_REGEX patterns.  XQuery says that:
* 's' allows the dot character to match newlines, which by
  default it will not;
* 'm' allows ^ and $ to match at newlines, not only at the
  start/end of the whole string.
Thus, these are *not* inverses as they are for the similarly-named
POSIX options, and neither one corresponds to the POSIX 'n' option.
Fortunately, Spencer's library does expose these two behaviors as
separately twiddlable flags, so we just have to fix the mapping from
JSP flag bits to REG flag bits.  I also chose to rename the symbol
for 's' to DOTALL, to make it clearer that it's not the inverse
of MLINE.

Also, XQuery says that if the 'q' flag "is used together with the m, s,
or x flag, that flag has no effect".  I read this as saying that 'q'
overrides the other flags; whoever wrote our code seems to have read
it backwards.

Lastly, while XQuery's 'x' flag is related to what Spencer's code
does for REG_EXPANDED, it's not the same or a subset.  It seems best
to treat XQuery's 'x' as unimplemented for now.  Maybe later we can
expand our regex code to offer 'x'-style parsing as a separate option.

While at it, refactor the jsonpath code so that (a) there's only
one copy of the flag transformation logic not two, and (b) the
processing of flags is independent of the order in which the flags
are written.

We need some documentation updates to go with this, but I'll
tackle that separately.

Back-patch to v12 where this code originated.
