Bring in a BumpPtrStringSaver from lld and simplify the interface.
StringSaver now always saves to a BumpPtrAllocator.
The only reason for having the virtual saveImpl is so lld can have a
thread safe version.
The reason for the distinct BumpPtrStringSaver class is to avoid the
virtual destructor.

Cleanup result_of tests and fix issues with the C++03 result_of.
The two main fixes this patch contains are:
- use __identity_t instead of common_type. common_type was used as an
identity metafunction but the decay resulted in incorrect results.
- Pointers to free functions were not counted as functions. Remove the pointer
before checking if a type is a function.

Fix PR12999 - unordered_set::insert calls operator new when no insert occurs
Summary:
when `unordered_set::insert(value_type&&)` was called it would be treated like `unordered_set::emplace(Args&&)` and it would allocate and construct a node before trying to insert it.
This caused unnecessary allocations when the value was already in the set. This patch adds an overload to `__hash_table::__insert_unique` that specifically handles `value_type&&` more link `value_type const &`.
This patch also adds a single unified insert function for values into `__hash_table` called `__insert_unique_value` that handles the cases for `__insert_unique(value_type&&)` and `__insert_unique(value_type const &)`.
This patch fixes PR12999: http://llvm.org/bugs/show_bug.cgi?id=12999.

Add `-verify-ignore-unexpected` option to ignore unexpected diagnostics in VerifyDiagnosticsConsumer
Summary:
The goal of this patch is to make `-verify` easier to use when testing libc++. The `notes` attached to compile error diagnostics are numerous and relatively unstable when they reference libc++ header internals. This patch allows libc++ to write stable compilation failure tests by allowing unexpected diagnostic messages to be ignored where they are not relevant.
This patch adds a new CC1 flag called `-verify-ignore-unexpected`. `-verify-ignore-unexpected` tells `VerifyDiagnosticsConsumer` to ignore *all* unexpected diagnostic messages. `-verify-ignore-unexpected=<LevelList>` can be used to only ignore certain diagnostic levels. `<LevelList>` is a comma separated list of diagnostic levels to ignore. The supported levels are `note`, `remark`, `warning` and `error`.

[LIT] Fix failing LIT tests
Summary:
I spend some time trying to get the LIT test suite passing. Here are the changes that I needed to make on my machine.
I made the following changes for the following reasons.
1. google-test.py: The Google test format now checks for "[ PASSED ] 1 test." to check if a test passes.
2. discovery.py: The output appears in a different order on my machine than it did in the test.
3. unittest-adaptor.py: The output appears in a different order on my machine than it did in the test.
4. The classname is now formed differently in `getJUnitXML(...)`.
I'm not sure what is causing the output order to differ in discovery.py and unittest-adaptor.py. Does anybody have any thoughts?

[libcxx] Use __decltype instead of __typeof__
Summary:
Both clang and GCC provide C++11 decltype semantics as __decltype in c++03 mode. We should use this instead of __typeof__ when availble.
GCC added __decltype in 4.6.0, and AFAIK clang provided __decltype ever since 3.3. Unfortunately `__has_builtin(__decltype)` doesn't work for clang so we need to check the compiler version instead.
