2f9dac721d Introduce the "@llvm.dbg.value" debug intrinsic. 
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.

An example:
  call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2)
Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.

faf815b938 Handle forwarding local memsets to loads. For example, we optimize this: 
short x(short *A) {
  memset(A, 1, sizeof(*A)*100);

}

to 'return 257' instead of doing the load.
