When testing with rte_hash library and TSX, a higher level of transaction
aborts was observed in some cases, especially with newer compilers.  These
patches reduce aborts by ensuring that the compiler does not accidentally
insert instructions that cause aborts, and by adding in delays on retry to
avoid repeated collisions.

  test/test: improve output for hash read-write test

  hash: fix extra TSX collisions with newer gcc
  hash: add local cache for TSX region
