[libcxx] Optimize vectors uninitialized construction of trivial types from an iterator range.
Summary:
In certain cases vector can use memcpy to construct a range of elements at the back of the vector. We currently don't do this resulting in terrible code gen in non-optimized mode and a
very large slowdown compared to libstdc++.
This patch adds a `__construct_forward_range(Allocator, Iter, Iter, _Ptr&)` and `__construct_forward_range(Allocator, Tp*, Tp*, Tp*&)` functions to `allocator_traits` which act similarly to the existing `__construct_forward(...)` functions.
This patch also changes vectors `__construct_at_end(Iter, Iter)` to be `__construct_at_end(Iter, Iter, SizeType)` where SizeType is the size of the range. `__construct_at_end(Iter, Iter, SizeType)` now calls `allocator_traits<Tp>::__construct_forward_range(...)`.
This patch is based off the design of `__swap_out_circular_buffer(...)` which uses `allocator_traits<Tp>::__construct_forward(...)`.
On my machine this code performs 4x better than the current implementation when tested against `std::vector<int>`.

It improves the v4i64 case although not optimally. This AVX codegen:

vxorpd %ymm1, %ymm1, %ymm1
vblendpd {{.*#+}} ymm0 = ymm0[0],ymm1[1,2,3]

Verifier: Move checks over from DIDescriptor::Verify()
Move over some more checks from `DIDescriptor::Verify()`, and change
`LLParser` to require non-null `file:` fields in compile units.
I've ignored the comment in test/Assembler/metadata-null-operands.ll
since I disagree with it. At the time that test was written (r229960),
the debug info verifier wasn't on by default, so my comment there is in
the context of not expecting the verifier to be useful. It is now, and
besides that, since r233394 we can check when parsing textual IR whether
an operand is null that shouldn't be.

Increate backlog of lldb-platform's listener socket
lldb-platform's listener socket only had a backlog of one connection.
That means that if more than one client connected simultaneously, the

DebugInfo: Remove LexicalBlockFile scope/context distinction
Two things here:
1. I read `getScope()` and `getContext()` backwards in r233640. There
was no need for `getScopeOfScope()`. Obviously not enough test
coverage here (as I said in that commit, I'm going to come back to
that), but anyway I'm reverting to the behaviour before r233640.
2. The callers that use `DILexicalBlockFile::getContext()` don't seem
to care about the difference. Just have it redirect to `getScope()`
so I can't get confused again.

LexicalScopes: Use debug info hierarchy pervasively
Pervasively use the types provided by the debug info hierarchy rather
than `MDNode` in `LexicalScopes`.
I noticed (again, I guess, based on comments in the implementation?)
that `DILexicalBlockFile::getScope()` returns something different from
`DILexicalBlockFile::getContext()`. I created a local helper for
getting the same logic from `MDLexicalBlockFile` called
`getScopeOfScope()`. I still don't really understand it, but I've added
some FIXMEs and I'll come back to it (I suspect the way we encode these
objects isn't really ideal).
Note that my previous commit r233610 accidentally changed behaviour in
`findLexicalScope()` -- it transitioned from a call to
`DILexicalBlockFile::getScope()` to `MDLexicalBlockFile::getScope()`
(sounds right, doesn't it?) -- so I've fixed that as a drive-by. No
tests failed with my error, so it looks like we're missing some coverage
here... when I come back to understand the logic, I'll see if I can add
some.
Other than the fix to `findLexicalScope()`, no functionality change.
