Alexander Potapenko 20f9fcc285 Move the prototype of __CFInitialize to asan_mac.h so that asan_malloc_mac.cc may use it in the dynamic library mode.

Bill Wendling e1c54262f4 Set the branch probability of branching to the 'normal' destination of an invoke 
instruction to something absurdly high, while setting the probability of
branching to the 'unwind' destination to the bare minimum. This should set cause
the normal destination's invoke blocks to be moved closer to the invoke.

Alexander Potapenko 9a168a7405 Use SANITIZER_INTERFACE_ATTRIBUTE instead of __attribute__((visibility("default"))) 
Export CheckFailed, asan_malloc, asan_free, asan_memalign, AsanStackTrace::CompressStack, AsanStackTrace::UncompressStack from the dynamic runtime library.

Alexey Samsonov 9fe914b099 [ASan] Port (the last one) tricky interface_test to lit, and a *huge* chunks of boilerplate to run tests for 32/64 bits and all optimization levels. Alas, lit doesn't support for loops in RUN-lines...

Hans Wennborg 420052640f Check for improper use of 'static' and type qualifiers in array 
declarators.

They are only allowed for function parameters, and then only on the
outermost array type derivation.

Michael Liao 69e172a6f0 fix infinite loop in instcombine with more than 4GB memcpy 
- memcpy size is wrongly truncated into 32-bit and treat 8GB memcpy is
  0-sized memcpy
- as 0-sized memcpy/memset is already removed before SimplifyMemTransfer
  and SimplifyMemSet in visitCallInst, replace 0 checking with
  assertions.
- replace getZExtValue() with getLimitedValue() according to
  Eli Friedman

Jordan Rose 5132aaeb04 [analyzer] Don't inline dynamic-dispatch methods unless -analyzer-ipa=dynamic. 
Previously we were checking -analyzer-ipa=dynamic-bifurcate only, and
unconditionally inlining everything else that had an available definition,
even under -analyzer-ipa=inlining (but not under -analyzer-ipa=none).

Jordan Rose 0f6d63be06 [analyzer] Correctly devirtualize virtual method calls in destructors. 
C++11 [class.cdtor]p4: When a virtual function is called directly or
  indirectly from a constructor or from a destructor, including during
  the construction or destruction of the class’s non-static data members,
  and the object to which the call applies is the object under
  construction or destruction, the function called is the final overrider
  in the constructor's or destructor's class and not one overriding it in
  a more-derived class.

Anton Korobeynikov c6d945b11a The names of VFP variants of half-to-float conversion instructions were 
reversed. This leads to wrong codegen for float-to-half conversion
intrinsics which are used to support storage-only fp16 type.
NEON variants of same instructions are fine.

Michael Liao 34107b9177 fix PR11334 
- FP_EXTEND only support extending from vectors with matching elements.
  This results in the scalarization of extending to v2f64 from v2f32,
  which will be legalized to v4f32 not matching with v2f64.
- add X86-specific VFPEXT supproting extending from v4f32 to v2f64.
- add BUILD_VECTOR lowering helper to recover back the original
  extending from v4f32 to v2f64.
- test case is enhanced to include different vector width.

Johnny Chen 25c0eb4a38 When trying to take snapshots of a watched variable, if the frame is unable to evaluate the variable expression, 
do not take the sanpshot and forget about the stop info.  It is possible that the variable expression has gone
out of scope, we'll revise the hit count due to the false alarms.
