Replace MemPromotion with Definitie Init in debug output.

Also replace memory-promotion with definite-init for DEBUG_TYPE and fix
a typo.

Teach copy_addr explosion to scalarize any generated loads so that we

Keep track of stores produced by exploded copy_addrs in the NonLoadUses
...
set. This is the last fix required to get copy_addr to forward to the
load in this trivial example from rdar://15170149:
func testTrivial(a : @inout Int) -> Int {
return a
}
on to more testing.

Fix -enable-copyaddr-forwarding to properly extract out the result of a large

aggregate store to forward to a smaller load, e.g. to feed a copyaddr of an
Int to a load of the Builtin.Int64 inside of it.

The Uses vector can grow now, ElementPromotion::doIt shouldn't iterate over

it with a for-each loop.

The AST type of the VarDecl is incorrect for bound generic structs and needs to be substituted.

Progress towards having memory promotion explode copy_addrs when necessary to

feed loads. The new behavior is currently only enabled by the
-enable-copyaddr-forwarding flag and is known broken, I'm working on it!
