Jakob Stoklund Olesen 8289f78569 Remove the isMoveInstr() hook.

Stuart Hastings 0125b6410a Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). This 
addresses a longstanding deficiency noted in many FIXMEs scattered
across all the targets.

This effectively moves the problem up one level, replacing eleven
FIXMEs in the targets with eight FIXMEs in CodeGen, plus one path
through FastISel where we actually supply a DebugLoc, fixing Radar
7421831.

Dan Gohman 779c69bbc5 Add a DebugLoc argument to TargetInstrInfo::copyRegToReg, so that it 
doesn't have to guess.

Dale Johannesen 4244d12769 Teach AnalyzeBranch, RemoveBranch and the branch 
folder to be tolerant of debug info following the
branch(es) at the end of a block.

Dan Gohman 047a767d74 Remove the target hook TargetInstrInfo::BlockHasNoFallThrough in favor of 
MachineBasicBlock::canFallThrough(), which is target-independent and more
thorough.

Chris Lattner a48f44d9ee improve portability to avoid conflicting with std::next in c++'0x. 
Patch by Howard Hinnant!

Dan Gohman be8137b0b4 Replace TargetInstrInfo::isInvariantLoad and its target-specific 
implementations with a new MachineInstr::isInvariantLoad, which uses
MachineMemOperands and is target-independent. This brings MachineLICM
and other functionality to targets which previously lacked an
isInvariantLoad implementation.
