The __ARM_FEATURE_SVE_BITS feature macro is specified in the Arm C
Language Extensions (ACLE) for SVE [1] (version 00bet5). From the spec,
where __ARM_FEATURE_SVE_BITS==N:

  When N is nonzero, indicates that the implementation is generating
  code for an N-bit SVE target and that the arm_sve_vector_bits(N)
  attribute is available.

This was defined in D83550 <https://reviews.llvm.org/D83550> as __ARM_FEATURE_SVE_BITS_EXPERIMENTAL and
enabled under the -msve-vector-bits flag to simplify initial tests.
This patch drops _EXPERIMENTAL now there is support for the feature.
