1784d160e4 The hasMemory argument is irrelevant to how the argument 
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

186b3d2606 If a metadata operand is seeded in value map and the metadata should also be seeded in value map. This is not limited to function local metadata. 
Failure to seed metdata in such cases causes troubles when in a cloned module, metadata from a new module refers to values in old module. Usually this results in mysterious bugpoint crashes. For example,

6da12e6767 Implement rdar://6295824 and PR6724 with two tiny changes 
that can have a big effect :).  The first is to enable the
iterative SCC passmanager juice that kicks in when the
scc passmgr detects that a function pass has devirtualized
a call.  In this case, it will rerun all the passes it 
manages on the SCC, up to the iteration count limit (4). This
is useful because a function pass may devirualize a call, and
we want the inliner to inline it, or pruneeh to infer stuff
about it, etc.

The second patch is to add *all* call sites to the 
DevirtualizedCalls list the inliner uses.  This list is
about to get renamed, but the jist of this is that the 
inliner now reconsiders *all* inlined call sites as candidates
for further inlining.  The intuition is this that in cases 
like this:

f() { g(1); }     g(int x) { h(x); }

We analyze this bottom up, and may decide that it isn't 
profitable to inline H into G.  Next step, we decide that it is
profitable to inline G into F, and do so, which means that F 
now calls H.  Even though the call from G -> H may not have been
profitable to inline, the call from F -> H may be (in this case
because a constant allows folding etc).

In my spot checks, this doesn't have a big impact on code.  For
example, the LLC output for 252.eon grew from 0.02% (from
317252 to 317308) and 176.gcc actually shrunk by .3% (from 1525612
to 1520964 bytes).  252.eon never iterated in the SCC Passmgr,
176.gcc iterated at most 1 time.
