Utilizing newer LLVM diagnostic remark API in order to enable use of
opt-viewer tool. Polly Diagnostic Remarks also now appear in YAML
remark file.
In this patch, I've added the OptimizationRemarkEmitter into certain
classes where remarks are being emitted and update the remark emit calls
itself. I also provide each remark a BasicBlock or Instruction from where
it is being called, in order to compute the hotness of the remark.

This single option replaces -polly-detect-unprofitable and -polly-no-early-exit
and is supposed to be the only option that disables compile-time heuristics that
aim to bail out early on scops that are believed to not benefit from Polly
optimizations.

Polly's profitability heuristic saves compile time by skipping trivial scops or
scops were we know no good optimization can be applied. For almost all our tests
this heuristic makes little sense as we aim for minimal test cases when testing
functionality. Hence, in almost all cases this heuristic is better be disabled.
In preparation of disabling Polly's compile time heuristic by default in the
test suite we first explicitly enable it in the couple of test cases that really
use it (or run with/without heuristic side-by-side).

I ran the script from r246327 and it touched all the right files;
committing now to hopefully right the bots, but if my check-polly
doesn't come back clean I'll keep looking.

I just learned that target triples prevent test cases to be run on other
architectures. Polly test cases are until now sufficiently target independent
to not require any target triples. Hence, we drop them.

Scops that only read seem generally uninteresting and scops that only write are
most likely initializations where there is also little to optimize. To not
waste compile time we bail early.
