Hexagon: Honor __builtin_expect by using branch probabilities.
* lib/Target/Hexagon/HexagonInstrInfo.cpp (GetDotNewPredOp):
Given a jump opcode return the right pred.new jump opcode with
a taken vs not-taken hint based on branch probabilities provided
by the target independent module.
* lib/Target/Hexagon/HexagonVLIWPacketizer.cpp: Use the above function.
* lib/Target/Hexagon/HexagonNewValueJump.cpp(getNewvalueJumpOpcode):
Enhance existing function use branch probabilities like
HexagonInstrInfo::GetDotNewPredOp but for New Value (GPR) Jumps.
