I need to insert `useAppleInternalSDK()` check here.

r=me. Such a complex feature, even before having to worry about ICU versions and Gregorian vs. Julian...
I really appreciate the detailed comments and thorough tests. #マジ乙

Seems like you could actually move this into createPart?

Is this used implicitly somewhere, or did it end up unnecessary?

Let's add a note here about the version-dependent failures.

Oops, I r+ed an obsolete patch. r+ing the latest one, contingent on making EWS happy.

That's good. Changed.

Yeah, originally, I thought ICU was producing right interval and we can split "literal" into ranges, but I ensured it isn't. So this function is not used. I'll drop it for now.

Added.

Only failed test was stress/intl-datetimeformat-formatrangetoparts.js, and this is because it is using formatRangeToParts in OSS WebKit.
I've fixed the test, and ensured it pass.

Hi, this reverted r269667. Was that an accident? It breaks all the tests that commit fixed. All the new tests are broken too (on Fedora 32 with ICU 65.1) since the code checks for ICU >= 67 rather than >= 65. E.g.:

This branch is making such test fail for ARMv7 and MIPS. This test passes if we have line #41 assignment running. We are using a very old ICU version (ICU 60) on buildbots and EWS.

Please skip them, or just adjust it.
I have no ability to support all ICU versions. The supported ones are ICU 64, 66, and 67 in my patch.
