Backporting to ICU 63. This is manually cherry-picked from
commit: 693adf3987
This fixes a regression introduced by commit
b12a927c93 for issue ICU-13778.
The above commit improved the error checking in the
DateTimePatternGenerator class, adding checks for errors/failures
where there previously was none at all. This was done in order to
catch catastrophic errors like out-of-memory (OOM), and properly
report them to the caller, rather than ignoring/hiding these errors.
However, in doing so it exposed a case where the code was depending
on ignoring errors in order to fall-back to the Gregorian calendar
when the default ICU locale is set to root.
This restores the previous behavior, by allowing the error of
U_MISSING_RESOURCE_ERROR to fall-though and continue without
reporting back an error to the caller.
Note: This regression was technically introduced in ICU 63, and
also effects ICU 64 as well.
- fastpath for UnicodeSet.add(new last range)
- fewer UnicodeSet memory allocations:
initial internal list array, exponential array growth,
allocate strings list/set only when first one is added
- faster CodePointTrie.getRange(): fewer calls to filter function
- revert UnicodeSet(intprop=value) from trie ranges to range starts + lookup
- cache per-int-prop range starts: fewer lookups

The macro _MSC_VER is not defined in other compilers.
Change the logic and so urename.h is ignored on VS IntelliSense
(cherry picked from commit ff72d74d1e)
This was fixed in earlier commits (see, for example, ICU-12786), but
the problem was reintroduced in commits f8ba68e and fcb82cb.

uloc_forLanguageTag has a few mapping tables to map grandfathered
language tags and deprecated language subtags to their preferred or
modern values.
Update them based on the latest version of the IANA
language subtag registry. [1]
Five grandfathered tags without a preferred value are still mapped to
what ICU has mapped them to for backward compatibility until the
wisdom of continuing to do so is reviewed.
In addition, map redundant language tags to their preferred values
regardless of whether they're followed by other subtags or not. (e.g.
zh-yue vs zh-yue-u-co-pinyin) .
Similary, ja-latn-hepburn-heploc is mapped to ja-latn-alaic97 (the
variant subtag 'hepburn-helploc' with the prefix 'ja-latn' has the
preferred value, 'alaic97') .
Update the mapping for deprecated language subtags (e.g. 'jw' to
'jv' and a bunch of 3-letter language codes).
Add a new table for deprecated region subtags to map them to their
modern values. (e.g. 'DD' to 'DE').
Add a new test case for deprecated language and region mapping and
a few more cases for updated grandfathered and redundant tag mapping.
