Patch by Andrew C. Morrow: shims to work around macroized getc and putc on linux. On my eglibc 2.13 based Debian system 'getc' is a macro defined in
...
/usr/include/stdio.h. This decision to make it a macro doesn't seem to
be guarded by any feature test macro as far as I can see.

Patch by Andrew C. Morrow: Conditionally include cxxabi.h in new.cpp and typeinfo.cpp. Both new.cpp and typeinfo.cpp have code that is conditionally compiled
...
based on the LIBCXXRT and _LIBCPPABI_VERSION defines, but those files
do not currently include <cxxabi.h> in the non __APPLE__ case. The
attached patch updates those files so that for non __APPLE__ builds
<cxxabi.h> is included if available or if LIBCXXRT is set. I'm
modeling this on the recent updates to exception.cpp.

<algorithm> no longer needs to include <cstdlib>, but can get away with just <cstddef>. This was brought to my attention by Salvatore Benedetto in his port to a bare-metal coretex-m3. This exposed two test bugs where an explicit #include <cstdlib> was needed.

Apple LWG 2067: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3318.html#2067 . This is the only actionable change that has been made to the C++ draft since C++11. In general it has not been decided exactly how libc++ will track changes made to C++11. New features and design changes will probably be #ifdef'd, especially if they are not backwards compatible. Defects and 'dumb mistakes' are more likely to just be put in. Decisions on telling one from the other will be made on a case by case basis.

Relax the complete-type checks that are happening under __invokable<Fp, Args...> to only check Fp, and not Args... . This should be sufficient to give the desired high quality diagnostics under both bind and function. And this allows a test reported by Rich E on cfe-dev to pass. Tracked by <rdar://problem/11880602>.

Apply constexpr to the mutex constructor. As a conforming extension, apply constexpr to the condition_variable constructor. These are important because it enables the compiler to construct these types at compile time, even though the object will be non-const. Since they are constructed at compile time, there is no chance of a data race before they are constructed.

This commit establishes a new bucket_count policy in the unordered containers: The policy now allows a power-of-2 number of buckets to be requested (and that request honored) by the client. And if the number of buckets is set to a power of 2, then the constraint of the hash to the number of buckets uses & instead of %. If the client does not specify a number of buckets, then the policy remains unchanged: a prime number of buckets is selected. The growth policy is that the number of buckets is roughly doubled when needed. While growing, either the prime, or the power-of-2 strategy will be preserved. There is a small run time cost for putting in this switch. For very cheap hash functions, e.g. identity for int, the cost can be as high as 18%. However with more typical use cases, e.g. strings, the cost is in the noise level. I've measured cases with very cheap hash functions (int) that using a power-of-2 number of buckets can make look up about twice as fast. However I've also noted that a power-of-2 number of buckets is more susceptible to accidental catastrophic collisions. Though I've also noted that accidental catastrophic collisions are also possible when using a prime number of buckets (but seems far less likely). In short, this patch adds an extra tuning knob for those clients trying to get the last bit of performance squeezed out of their hash containers. Casual users of the hash containers will not notice the introduction of this tuning knob. Those clients who swear by power-of-2 hash containers can now opt-in to that strategy. Clients who prefer a prime number of buckets can continue as they have.

Fixed a bug regarding result_of reported by Sven Behne. The fix is C++11 only mainly because result_of is a variadic beast and working with variadics is just such a problem in C++03 mode. This should bring result_of up to full conformance with the C++11 spec.
