[RyuJIT/ARM32] Enable passing large split struct argument (#12050)
* [RyuJIT/ARM32] Enable passing large split struct
This enables passing split struct larger than 16 bytes.
To support splitted struct, it defines new GenTree type - GenTreePutArgSplit.
GenTreePutArgSplit is similar with GenTreePutArgStk,
but it is used for splitted struct only
and it has additional field to save register information.
GenTreePutArgSplit node is generated in lower phase.
* Apply reviews: split struct argument passing
- Fix some comments:
genPutArgSplit, GenTreePutArgStk, GenTreePutArgSplit, NuwPutArg, ArgComplete
- Add assertion check in genPutArgSplit, genCallInstruction
- Rename variable: baseReg
- Change flag for GenTreePutArgSplit: _TARGET_ARM && !LEGACY_BACKEND
- Change type of gtOtherRegs in GenTreePutArgSplit
- Remove duplicated code: NewPutArg
- Implement spill & restore flag for GenTreePutArgSplit
* Apply reviews
- Rebase
- Update managing spillFlag for split struct
- Implement spill & restore code generation
- Fix typos and rename variables
- Fix bug related to print gentree for split struct
* Fix bug and comments
- Fix bug in regset.cpp
- Add comments in morph.cpp's NYI_ARM
- Fix comments' typo in lsraarmarcp.cpp
