This is the core execution bits of OpenACC reductions.
We have a new internal fn 'IFN_GOACC_REDUCTION' and a new target hook
goacc.reduction, to lower it on the target compiler.
So, let me start with a few questions:
1) does OpenACC allow UDRs or only the built-in reductions? If it
does not allow UDRs, do you have it covered by testcases that you
disallow parsing of them (e.g. when you have
no UDR reductions. Will check test cases for that.
BTW, what about min/max reductions for C/C++? Those were added in OpenMP
3.1, so perhaps OpenACC copied them.
OpenACC has min/max, and this is exercised on gomp4. we'll get to porting more
testcases after this rush is done, ok? (Or is there something specific about
min/max?)
