[LLVMdev] Running the test suite with special opt flags

Hi Hal, I think the testsuite has support for "opt-beta" which means
running opt with special flags side by side with the usual opt.
TEST.nightly.Makefile turns this on with ENABLE_OPTBETA.  I took a
peek at Makefile.programs to see how it is implemented, and as far
as I can see it can't possibly actually work :(  So probably the
simplest thing is to run the testsuite once to get a baseline, then
hard-wire these options on in std-compile-opts and run the testsuite

Ciao, Duncan.
