This is a big PR and thanks for working on it. Overall, looks good except some nit comments. Also, please run the tests, including the stress tests and share the results.

Looking at #102180 reminded me that we can do the following....

For NI_Sve_Store remove the Special Code Gen flag and this case statement. This will cause the generic code to call emitIns_R_R_R().

You can now add a special case in emitIns_R_R_R() so that for NI_Sve_Store it just calls down to emitIns_R_R_R_I() with 0 for the immediate. Eg:

case INS_sve_ld1b:

Curious...

NI_AdvSimd_Store uses gtNewSimdStoreNode() which eventually gets generated in genCodeForStoreInd(). This has extra code, for example, isvolatile checks.

Meanwhile NI_AdvSimd_StoreSelectedScalar imports like a normal hwintrinsic and gets generated in hwintrinsiccodegenarm64.cpp. This is the same for the various other stores.

Is there a special reason for using genCodeForStoreInd?

Why do the other stores not use genCodeForStoreInd?

Should NI_Sve_Store use genCodeForStoreInd?

As noted in #102180 (comment), these should be StoreAndZip APIs instead of Store APIs because of the operation it is performing.

Similar API was named as StoreAndZip in AdvSimd.
