Ed Schouten 7893e6874d Add some basic support for CloudABI on i686.
Some people want to experiment with building i686 CloudABI binaries. I
am not entirely sure this is a good idea, as I'd rather see Intel x32
support appear.

As it only requires a two-line change, let's at least provide compiler
to ease experimenting.

Rafael Espindola 454adf6454 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.

Eric Fiselier d9ad0cbd70 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.

Eric Fiselier de3f2b396c 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.

Eric Fiselier 098e6de9aa 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`.

Eric Fiselier 8fcf50515b [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?

Eric Fiselier f817754627 [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.

Matt Wala 1f48192d7c [Scalarizer] Fix potential for stale data in Scattered across invocations
Summary:
Scalarizer has two data structures that hold information about changes
to the function, Gathered and Scattered. These are cleared in finish()
at the end of runOnFunction() if finish() detects any changes to the
function. 

However, finish() was checking for changes by only checking if
Gathered was non-empty. The function visitStore() only modifies
Scattered without touching Gathered. As a result, Scattered could have
ended up having stale data if Scalarizer only scalarized store
instructions. Since the data in Scattered is used during the execution
of the pass, this introduced dangling pointer errors. 

The fix is to check whether both Scattered and Gathered are empty
before deciding what to do in finish().
