[PATCH] D34284: [StringRef] Make getAsInteger a tad more robust.

[Zachary Turner via Phabricator via llvm-commits]

  Previously if the auto sense radix was specified as part of
  the string and you *also* explicitly specified the radix value
  to the function, we would fail.
  
  This patch allows the radix prefix to be properly consumed even
  in non-auto-sense mode.
  
  In doing so, I learned that there was zero test coverage for
  getAsInteger with an explicitly specified radix, so this patch
  also rectifies that since I needed to add tests to make sure
  this patch works.
