8513d4236c docs/doxygen.css: Tweak style for readability. 
A few styles are brought from http://llvm.org/test-doxygen/api/api.css

b2e1a5c998 Add a utility function smart_iter() which has knowledge of the getsize and the getelem 
method names of all the lldb container objects and returns an iterator object when
passed an eligible lldb container object.

Example:

    from lldb_util import smart_iter
    for thread in smart_iter(process):
        ID = thread.GetThreadID()
        if thread.GetStopReason() == lldb.eStopReasonBreakpoint:
            stopped_due_to_breakpoint = True
        for frame in smart_iter(thread):
            self.assertTrue(frame.GetThread().GetThreadID() == ID)
        ...

Add a test case for lldb.smart_iter().

9808d31b9e If converter was being too cute. It look for root BBs (which don't have 
successors) and use inverse depth first search to traverse the BBs. However
that doesn't work when the CFG has infinite loops. Simply do a linear
traversal of all BBs work just fine.

ede9d33cde Heh, funny thing, 'void' isn't a POD type. Nice of us to suggest it to 
silence this warning. ;]

6825eebcd6 This is the next step in building the standalone tools infrastructure: 
This patch simplifies writing of standalone Clang tools. As an
example, we add clang-check, a tool that runs a syntax only frontend
action over a .cc file. When you integrate this into your favorite
editor, you get much faster feedback on your compilation errors, thus
reducing your feedback cycle especially when writing new code.

The tool depends on integration of an outstanding patch to CMake to
work which allows you to always have a current compile command
database in your cmake output directory when you set
CMAKE_EXPORT_COMPILE_COMMANDS.

005b5c1aee More accurately model realloc() when the size argument is 0. realloc() with a size of 0 is equivalent to free(). The memory region should be marked as free and not used again.

085ad3b81a Stop trying to have instcombine preserve LCSSA form: this was not 
effective in avoiding recomputation of LCSSA form; the widespread
use of instsimplify (which looks through phi nodes) means it was
not preserving LCSSA form anyway; and instcombine is no longer
scheduled in the middle of the loop passes so this doesn't matter
anymore.

53caa4d4fa Add a warning (-Wnon-pod-memset) for calls to memset() with 
a destination pointer that points to a non-POD type. This can flag such
horrible bugs as overwriting vptrs when a previously POD structure is
suddenly given a virtual method, or creating objects that crash on
practically any use by zero-ing out a member when its changed from
a const char* to a std::string, etc.

08b434f450 Allow 'Environment::getSVal()' to allow an optional way for checkers to do a direct lookup to values bound to expressions, without

8b02cd0bea Extend Sema::ClassifyName() to support C++, ironing out a few issues 
in the classification of template names and using declarations. We now
properly typo-correct the leading identifiers in statements to types,
templates, values, etc. As an added bonus, this reduces the number of
lookups required for disambiguation.
