Vlad Tsyrklevich a0b02833bc Limit CFI blacklist entries to specific CFI mode 
Summary:
Since D37924 and D37925 were merged, it's now possible to specify
individual sanitizers or CFI modes in sanitizer blacklists. Update the
CFI blacklist entries to only apply to cfi-unrelated-cast checks.

Vlad Tsyrklevich 8d7755e7aa CFI: Move STL allocator blacklist to clang 
Summary:
The regular expression to match STL allocators can't easily account for
C++ mangling compression and fails to match some valid instances of STL
allocators. Perform this logic in clang instead.

Motivated by crbug.com/751385.

Peter Collingbourne 44781f1b0c CFI: Add a blacklist entry for std::_Sp_counted_ptr_inplace::_Sp_counted_ptr_inplace(). 
This ctor is used by std::make_shared and needs to cast to uninitialized T*
in order to call std::allocator_traits<T>::construct.
