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 &)`.

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().

[builtins] Hide long double fp_test.h helpers if it's not fp128.

Like we do for the various __*tf* tests, check that long double is the
128bit type we expect directly in the header. The latter is now used by
unrelated tests (__*hf* since r237161), and those tests will break for
no reason if uint128_t doesn't exist, and long double isn't fp128.

9 years agoRefix a use of explicit pointer types in GEP constant folding

Refix a use of explicit pointer types in GEP constant folding

In the glorious future of opaque pointer types, it won't be possible to
retrieve the pointee type of a pointer type which is what's being done
in this GEP loop - but the first iteration is always a pointer type and
the loop doesn't care about that case, except whether or not the index
is a constant.

So pull that special case out before the loop and start at the second
iteration (index 1) instead.

Originally committed in r236670 and reverted with a test case in
r239015. This change keeps the test case working while also avoiding
depending on pointee types.

9 years ago[MS ABI] Lock-in the derived memptr rep. for base-to-derived conversions

We would get this right in the case where an explicit cast was formed
