Title:
  [23.10 FEAT] libgmp SIMD optimizations

Status in Ubuntu on IBM z Systems:
  Fix Released
Status in gmp package in Ubuntu:
  Fix Released

Bug description:
  Optimize the GNU MP Bignum Library using vector instructions.

  - Requirement for Full Homomorphic Encryption, libgmp is used as a backend for NTL
  - libgmp performance is critical also for GNU Cobol on Z.
  Here a customer requested using packed decimal instructions in libgmp which does not appear to fit for libgmp - however SIMD would help on distros with ALS z13
