I think the test case should also include "-mcpu=vulcan" with the new
version to ensure that the backwards compatibility does in fact still
work.

Title:
  add support for thunderx2 cores

Bug description:
  [Impact]
  gcc-5 doesn't know about thunderx2 cores, so optimization flags for this target will fail. While it is possible to generate the same code by referencing the previous name of the core (vulcan), that is non-obvious to the end user.

  [Test Case]
  gcc-5 hello.c -o hello -mcpu=thunderx2t99
  hello.c:1:0: error: unknown value ‘thunderx2t99’ for -mcpu
   #include <stdio.h>
   ^

  [Regression Risk]
  The patchset includes a rename of the "vulcan" core to "thunderx2t99". It retains backwards compatibility with the "vulcan" name to avoid regressing users that may already be using that name.
