The test used to fail with an invalid phi node: the two predecessors were outlined
and the SSA representation was left invalid. The patch adds the exit block to the
cold region.

remove duplicate entries from isSingleEntrySingleExit: the Entry block is
already added by the loop over the dominance frontier.
Remove the heuristic from isOutlineCandidate that a region is too small when it
only contains a basic block. With this change we now grow regions starting from
a block and we continue adding to the ValidColdRegion. Check the heuristic just
before code generation.

Also fix a problem in forward propagation:
const TerminatorInst *TI = It->getTerminator();
was set outside the while loop that iterates over It.

Before tagging a function with coldcc make sure the target supports cold calling
convention. Without this patch HotColdSplitting pass fails on aarch64 with:
fatal error: error in backend: Unsupported calling convention.

Find cold blocks based on profile information (or optionally with static analysis).
Forward propagate profile information to all cold-blocks.
Outline a cold region.
Set calling conv and prof hint for the callsite of the outlined function.
