Dan Gohman bd59d7b603 Implement more aggressive folding of add operand lists when ...

they contain multiplications of constants with add operations.
This helps simplify several kinds of things; in particular it
helps simplify expressions like ((-1 * (%a + %b)) + %a) to %b,
as expressions like this often come up in loop trip count
computations.

DebugInfo

llvm.dbg.region.end() intrinsic is not required to be in _last_ basic block in a function. If that happens then any basic block that follows (lexically) the block with regin.end will not have scope info available. LexicalScopeStack relies on processing basic block in CFG order, but this processing order is not guaranteed. Things get complicated when the optimizer gets a chance to optimizer IR with dbg intrinsics.
