disabling it removes some bogus diagnostics (see 2236).

idea what this code (findNonImmUse) does, so I'm only guessing 
that this is the right thing.  It would be really really nice
if this had comments and perhaps switched to SmallPtrSet
(hint hint) :)

This fixes rdar://5886601, a crash on gcc.target/i386/sse4_1-pblendw.c

goes back to the block, e.g.:

  Threading edge through bool from 'bb37.us.thread3829' to 'bb37.us' with cost: 1, across block:

bb37.us:		; preds = %bb37.us.thread3829, %bb37.us, %bb33
	%D1361.1.us = phi i32 [ %tmp36, %bb33 ], [ %D1361.1.us, %bb37.us ], [ 0, %bb37.us.thread3829 ]		; <i32> [#uses=2]
	%tmp39.us = icmp eq i32 %D1361.1.us, 0		; <i1> [#uses=1]
	br i1 %tmp39.us, label %bb37.us, label %bb42.us

Don't emit empty strings for path diagnostics when taking the default branch of a switch statement that has no label.

Implemented support for better localized leaks in the CF reference count checker.
Now leaks should be flagged close to where they occur.

This should implement the desired functionality in <rdar://problem/5879592>, although the diagnostics still need to be improved.

Fix bug in x86 memcpy / memset lowering. If there are trailing bytes not handled by rep instructions, a new memcpy / memset is introduced for them. However, since source / destination addresses are already adjusted, their offsets should be zero.

Part of this change resulted in creating sparser summaries.  I also added
some more comments and did some minor code cleanups.
