[AArch64-SVE]: Test enabling streaming mode for tests of: shifts, extract subverter, build vector, concat, and extract vector elt

[hassnaa-arm]

Summary

Test if the generated code is compatible to streaming mode for these new tests:
sve-streaming-fixed-length-int-shifts.ll
sve-streaming-mode-extract-subvector.ll
sve-streaming-mode-fixed-length-build-vector.ll
sve-streaming-mode-fixed-length-concat.ll
sve-streaming-mode-fixed-length-extract-vector-elt.ll
sve-streaming-mode-fixed-length-shuffle.ll
sve-streaming-mode-fixed-length-masked-load.ll
sve-streaming-mode-fixed-length-masked-store.ll
sve-streaming-mode-fixed-length-ext-loads.ll
sve-streaming-mode-fixed-length-trunc-stores.ll

I wonder if it's worth adding tests for extracting subvectors with i1 elements, i.e.

%ret = call <4 x i1> @llvm.vector.extract.v4i1.v8i1(<8 x i1> %op, i64 4)

etc.? If it doesn't just work we can always do the i1 types in a follow-on patch!

It might be good to test build_vector for floating point types as well, e.g. half, float, double, etc. Also might be worth checking that this works:

store <4 x i1> <i1 true, i1 false, i1 true, i1 false>

or something like that?

[hassnaa-arm]

Add shuffle test. add floating-point tests to build_vector test.

Update by parent patch

Test files of this patch are moved to another patch that has changes related to them, so no need for this patch now.
