We created them as `new (this, GT_INDEX_ADDR) GenTreeIndexAddr` but used smaller `GenTreeIndex` as nessecary size.

* Use LargeOpOpcode instead of GT_CALL.

follow the ICU User Guide recommendation to optimize the perf of InvariantCultureIgnoreCase on Linux (dotnet/coreclr#24889)

* follow the ICU User Guide recommendation to optimize the perf of InvariantCultureIgnoreCase on Linux:

1. try to guess the max size and call ucol_getSortKey just once
2. if the buffer is not big enough, call the method again providing the actual sort key length

* handle 0 case

* handle integer overflow

* shorten the time the buffers are pinned

* use the cheapest pinning

* code review fixes: don't use variable length stackalloc, don't copy text from docs (licensing) + don't try to go with the fast path when it would require allocating more managed memory for big strings

* simplify the condition

Flush() behaves like Flush(false) and writes out any buffered data but doesn't P/Invoke to FlushFileBuffers/FSync to flush the OS buffers.

But whereas FlushAsync() is supposed to just be an async equivalent of Flush(), it's actually behaving like Flush(true).  This makes FlushAsync() inconsistent and much more expensive.  (This is separate from FlushAsync not actually being async, which is an impactful problem to be solved separately.)

This changes FlushAsync to behave like Flush()/Flush(false) rather than Flush(true).  If someone wants the FlushFileBuffers/FSync behavior, they can call Flush(true).

Commit migrated from https://github.com/dotnet/coreclr/commit/0d21b57657f8135622797f0db29460c975dd2339

When adding the signature copying some time ago, I have overlooked one
place where the moduleIndex was set to -1 instead of MODULE_INDEX_NONE.
I was using the -1 during the development and replaced it by creating
MODULE_INDEX_NONE during final cleanup at all but one places.

This caused issues during crossgen even without large version bubble
enabled. Methods requiring generic constraint were not crossgen-ed due
to this.
