6ad0679106 Make a deep copy of SILDebugScopes when doing a SILBasicBlock::splice()> 
The cloned abstract variables may end up having different types
so they need to be distinct from the originals.

This fixes an crash/assertion in the LLVM backend.

c97ab1f11f [func-sig-opts] When splicing BB from one function to another, change 
the debug scope of each instruction to be the debug scope of the new
function.

This will be tested by the functionality in function signature opts.

ed124f6651 [func-sig-opts] Expose the ValueDecl argument of SILArgument's 
constructor in SILBasicBlock::createArgument.

By default the argument is nullptr so any place that currently does not
need to pass in the ValueDecl will not need to be updated given the new
behavior.

d3b9679795 Add the method SILArgument::getIncomingValues and refactor SILArgument implementation from SILBasicBlock.cpp => SILArgument.cpp. 
SILArgument::getIncomingValues() takes in an out array parameter and attempts to
gather up all values from the SILArguments parents predecessors whose value the
SILArgument could take on.

This will let me refactor the single predecessor handling code to also handle
multiple predecessors in a simple way.

225a5ca87b [func-sig-opts] Add the call SILFunction::spliceBody() to splice a function's body onto another function. 
I also added code to ilist_traits so we can set the parent function on BB to be the new function.

0f7053bd01 Remove SILBasicBlock::getBBArgIndex(SILArgument *) in favor of SILArgument::getIndex(). 
The index is a property of the argument. There is no reason from a modeling
perspective to go through the BB to get it.

8156008cd8 Add a dead code elimination optimization pass. 
In a loop like this:
  var j = 2
  for var i = 0; i < 100; ++i {
    j += 3
  }
it will completely eliminate j.

It does not yet support rewriting conditional branches as unconditional
branches in the cases where only empty blocks are control dependent on
an edge. Once this support is added, it will also completely eliminate
the loop itself.

924e30ea61 Rewrite BB args whose only use is in struct/tuple extract. 
If we have BB args that are only used in a struct/tuple extract, and
that are generated in each predecessor with a struct/tuple instruction,
retype the BB arg and replace the argument with what would have been the
extracted value.

This provides more opportunties for jump threading to kick in.

8f5b8ccb02 Rename "This" to "Self" and "this" to "self". 
This was not likely an error-free change.  Where you see problems
please correct them.  This went through a fairly tedious audit
before committing, but comments might have been changed incorrectly,
not changed at all, etc.
