  TME is a future architecture technology, documented in
  
  https://developer.arm.com/architectures/cpu-architecture/a-profile/exploration-tools
  https://developer.arm.com/docs/ddi0601/a
  
  More about the future architectures:
  
  https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/new-technologies-for-the-arm-a-profile-architecture
  
  This patch adds support for the TME instructions TSTART, TTEST, TCOMMIT, and
  TCANCEL and the target feature/arch extension "tme".
  
  It also implements TME builtin functions, defined in ACLE Q2 2019
  (https://developer.arm.com/docs/101028/latest)
