Implement a new type trait __is_trivially_constructible(T, Args...)
...
that provides the behavior of the C++11 library trait
std::is_trivially_constructible<T, Args...>, which can't be
implemented purely as a library.
Since __is_trivially_constructible can have zero or more arguments, I
needed to add Yet Another Type Trait Expression Class, this one
handling arbitrary arguments. The next step will be to migrate
UnaryTypeTrait and BinaryTypeTrait over to this new, more general
TypeTrait class.

The following patch adds __attribute__((no_address_safety_analysis)) which will allow to disable
...
address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a specific function.
When building with AddressSanitizer, add AddressSafety function attribute to every generated function
except for those that have __attribute__((no_address_safety_analysis)).
With this patch we will be able to
1. disable AddressSanitizer for a particular function
2. disable AddressSanitizer-hostile optimizations (such as some cases of load widening) when AddressSanitizer is on.

Thread Safety: Added basic argument parsing for all new attributes.
...
This patch special cases the parser for thread safety attributes so that all
attribute arguments are put in the argument list (instead of a special
parameter) since arguments may not otherwise resolve correctly without two-token
lookahead.
This patch also adds checks to make sure that attribute arguments are
lockable objects.
