[PATCH v2 0/7] aarch64: Add support for FEAT_SME_F16F16 feature and instructions.

[Srinath Parvathaneni]

Hi,

Changes from v1 -> v2:

* In the testcases, -march=armv9.4-a+sme-f16f16 changed to
  -march=armv8-a+sme-f16f16.
* In 4/7, additional tests for index in the three operands
  are added.
* Added ` ?` to the vector lists in the tests with z vectors
  - e.g. `{z0\.h-z3\.h}` -> `{ ?z0\.h-z3\.h ?}`.
