23bedf2b9b doxygenate RefreshCallGraph, add a new 'verification mode', and run it after 
CGSCC passes make change to ensure they are updating the callgraph correctly
(when assertions are enabled).

2c2c37b2b1 enhance memcpy opt to turn memmoves into memcpy when the src/dest 
don't alias.  Remove an old and poorly reduced testcase that fails
with this transform for reasons unrelated to the original test.

aren't supported anyway).

64e31dbd71 Preparation for Optimal Edge Profiling: 
Add statistics for regular edge profiling, this enables the comparation of the
number of edges inserted by regular and optimal edge profiling.

dc55b65b4c Preparation for Optimal Edge Profiling: 
Optimal edge profiling is only possible when blocks with no predecessors get an
virtual edge (BB,0) that counts the execution frequencies of this
function-exiting blocks.
This patch makes the necessary changes before actually enabling optimal edge profiling.

d2c2f12f1e Preparation for Optimal Edge Profiling: 
This adds a pass to verify the current profile against the flow conditions.
This is very helpful when later on trying to perserve the profiling information
during all passes.

53698d7fd7 Change CallGraphNode to maintain it's Function as an AssertingVH 
for sanity.  This didn't turn up any bugs.

Change CallGraphNode to maintain its "callsite" information in the 
call edges list as a WeakVH instead of as an instruction*.  This fixes
a broad class of dangling pointer bugs, and makes CallGraph have a number
of useful invariants again.  This fixes the class of problem indicated
by PR4029 and PR3601.

03f5a5bfff Fix pr4843: When an instruction has multiple destination registers that are 
tied to different source registers, the TwoAddressInstructionPass needs to
be smarter.  Change it to check before replacing a source register whether
that source register is tied to a different destination register, and if so,
defer handling it until a subsequent iteration.

9a220088ac Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

297360e2b1 Extend the ValuesAtScope cache to cover all expressions, not just 
SCEVUnknowns, as the non-SCEVUnknown cases in the getSCEVAtScope code
can also end up repeatedly climing through the same expression trees,
which can be unusably slow when the trees are very tall.

Also, add a quick check for SCEV pointer equality to the main
SCEV comparison routine, as the full comparison code can be expensive
in the case of large expression trees.

These fix compile-time problems in some pathlogical cases.
