Nuno Lopes 1e8dffdf27 BoundsChecking: optimize out the check for offset < 0 if size is known to be >= 0 (signed).
(LLVM optimizers cannot do this optimization by themselves)

Unfortunately this change requires the cache map to hold WeakVHs instead

Alexey Samsonov 961276af26 [Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections. To symbolize an address from a module, map this module to memory and obtain pointers to debug info sections. Later these pointers can be passed to constructor of DWARF context-in-memory from LLVM DebugInfo lib.

Chandler Carruth 9f0e4a2f18 Micro-optimize this function a bit. This shrinks the generated code
some, and allows the routine to be inlined into common callers. The
various bits that hit this code in their hotpath seem slightly lower on
the profile, but I can't really measure a performance improvement as
everything seems to still be bottlenecked on likely cache misses. =/

NAKAMURA Takumi 2a4930c96a llvm/test/lit.cfg: Retweak for Win32 to fix testing.
- execute_external should be;
    - Not on Win32.
    - Using bash.
    In reverse, "execute_internal" shoud be (Win32 && !bash).

  - lit.getBashPath() behaves differently before and after tweaking $PATH.

I will add a few explanations there later.

Chandler Carruth c4702dac1c Remove a redundant assignment to the FDecl variable from *inside* it's
initializer.

I really feel like Clang should warn about this, but I can't describe
a good reason. GCC will warn on this in some cases under
-Wsequence-point, but it actually seems like a false positive for that
warning....

John McCall 4e8ca4fa14 Significantly simplify CGExprAgg's logic about ignored results:
if we want to ignore a result, the Dest will be null.  Otherwise,
we must copy into it.  This means we need to ensure a slot when
loading from a volatile l-value.

With all that in place, fix a bug with chained assignments into
__block variables of aggregate type where we were losing insight into
the actual source of the value during the second assignment.

Argyrios Kyrtzidis b6df682194 [libclang] Introduce clang_Cursor_isDynamicCall which,
given a cursor pointing to a C++ method call or an ObjC message,
returns non-zero if the method/message is "dynamic", meaning:

  For a C++ method: the call is virtual.
  For an ObjC message: the receiver is an object instance, not 'super' or a
  specific class.

Chandler Carruth 34263a0c95 All glory to address sanitizer. ;]
It appears to have caught a use-after-free introduced as by r159567
and/or friends which call 'addPass' from many more places. The bug in
'addPass' doesn't appear to be new, and was spotted by inspection when
ASan shown a bright light of a stacktrace at these functions.

Hopefully this will fix the ASan failure -- I have no test case other
than running an ASan-built clang over the test suite.
