[test-suite] r251431 - [test-suite] Introduce a new CMake+LIT based harness

[James Molloy via llvm-commits]

Hi David,

Firstly, I tried to reply to this on my wonky hotel wifi last night (and
failed) so apologies if my devices spontaneously wake up and you receive
three different permutations of this email :)

I'm as keen as you to make this transition swift. The important thing is
that it *is* a transition - it's not another extra build system. Previous
email threads have concluded that noone (who piped up) is using the more
advanced features of the Makefile system.

The things that need improvement/implementing before we can switch
completely  are (non exhaustive):
  * Add support for cross-compilation (compiling timeit/fpcmp on the host)
  * Add support for Externals
  * Add options for number of reruns
  * Plumb into LNT (alongside the existing Makefile implementation) -
that's the one that's probably the most involved
  * Switch over buildbots, staggered, over a period.

Timescales are really hard to estimate or commit to, but the buildbot
switchover itself is likely to be at least 1-2 weeks as the new solution
needs to soak to find any bugs.

Suffice to say I'm keen to push this on.

Cheers,

James
