Chris Lattner 0f4a64011e Implement rdar://9009151, transforming strided loop stores of 
unsplatable values into memset_pattern16 when it is available
(recent darwins).  This transforms lots of strided loop stores
of ints for example, like 5 in vpr:

  Formed memset:   call void @memset_pattern16(i8* %4, i8* getelementptr inbounds ([16 x i8]* @.memset_pattern9, i32 0, i32 0), i64 %tmp25)
    from store to: {%3,+,4}<%11> at:   store i32 3, i32* %scevgep, align 4, !tbaa !4

Douglas Gregor bf2b26d805 The member classes of a current instantiation aren't necessarily a 
current instantiation, even though we have a RecordDecl describing
them. Fixes PR9255.

Amusingly, I've had this patch sitting around for a month or two
because it was "obviously" wrong, but hadn't gotten around to writing
a test case to submit the fix :)

Douglas Gregor 0cf82f6ad0 Teach the virtual-functions-without-virtual-destructor warning to only 
warn about polymorphic classes (which have virtual functions) rather
than dynamic classes (which are polymorphic or have virtual bases).

Douglas Gregor b11aad8cba Revert all of my commits that devirtualized the Decl hierarchy, which 
lead to a serious slowdown (4%) on parsing of Cocoa.h. This memory
optimization should be revisited later, when we have time to look at
the generated code.

Jeffrey Yasskin 39a5820059 Use PARSE_ARGUMENTS to clean up add_clang_unittest's calling convention. 
It would be nice to propagate this into the other functions to replace
LLVM_LINK_COMPONENTS and friends, but I don't plan to do that.

Jeffrey Yasskin ecdd68d760 Remove support and mc from the clang unittests' dependencies because they're not 
needed or provided by the libraries under test.

The next step is to import http://www.itk.org/Wiki/CMakeMacroParseArguments to
make the empty string parameter unnecessary.

John McCall 68cc3350a8 Fix a -Wuninitialized warning; it's actually a false positive, 
but it's not reasonable for the diagnostic to figure that out.
Pointed out by Benjamin Kramer.

John McCall 8377967543 Warn about code that uses variables and functions with internal linkage 
without defining them.  This should be an error, but I'm paranoid about
"uses" that end up not actually requiring a definition.  I'll revisit later.

Also, teach IR generation to not set internal linkage on variable
declarations, just for safety's sake.  Doing so produces an invalid module
if the variable is not ultimately defined.

Also, fix several places in the test suite where we were using internal
functions without definitions.

Jim Ingham 85e8b81492 - Changed all the places where CommandObjectReturn was exporting a StreamString to just exporting 
a Stream, and then added GetOutputData & GetErrorData to get the accumulated data.
- Added a StreamTee that will tee output to two provided lldb::StreamSP's.
- Made the CommandObjectReturn use this so you can Tee the results immediately to
the debuggers output file, as well as saving up the results to return when the command
is done executing.
- HandleCommands now uses this so that if you have a set of commands that continue the target
you will see the commands come out as they are processed.
- The Driver now uses this to output the command results as you go, which makes the interface
more reactive seeming.

Ted Kremenek fda3687515 Add 'StoreRef' smart pointer to allow more fine-grain memory lifetime control of Store objects. 
This yields a minor memory reduction (for larger functions) on Sqlite at the cost of slightly
higher memory usage on some functions because of the increased size of GRState (which can be optimized).

I expect the real memory savings from this enhancement will come when we aggressively
canabilize more of the ExplodedGraph.

Johnny Chen ce0dec7597 Make the helper method ReadCoreReg(uint32_t reg, bool *success) more generic 
which now handles R0-R12, SP, LR, as well as PC.  And refactored a lot of
calls to ReadRegisterUnsigned() to now funnel through ReadCoreReg(), instead.
