[LLVMdev] Changes in llvm::Instruction and subclasses

[Alkis Evlogimenos]

This should not affect current code but it may help people who deal with
LLVM instructions. Up till now one could create an llvm::Instruction
(and subclasses) using the following constructor:

Instruction(const Type *Ty, unsigned iType, const std::string &Name ="",
            Instruction *InsertBefore = 0);

If InsertBefore was specified the instruction was added to the basic
block InsertBefore was in, right after InsertBefore. While writing my
frontend this was never the case; I always wanted to append to the end
of a basic block. So I introduced this constructor variant:

Instruction(const Type *Ty, unsigned iType, const std::string &Name,
            BasicBlock *InsertAtEnd);

which inserts the newly created instruction to the end of InsertAtEnd
basic block.

I hope others will find this useful.
