Implement LWG 2193. Default constructors for standard library containers are explicit. Note that libc++ already did this for string/deque/forward_list/list/vector and the unordered containers; implement it for set/multiset/map/multimap. Add tests for all the containers. Two drive-by fixes as well: add a missing explicit in <deque>, and remove a tab that snuck into a container test. This issue is also LLVM bug 15724, and resolves it.

Scope lives in Sema and cannot be used in AST. Shuffle things around.

Remove definition of std::fmaf from libc++. Fixes bug #18910. This function should come from the C standard library. As a drive-by fix, update the tests to remove a warning from -Wabsolute-value

[C++11] Using std::unique_ptr to ensure that Argument objects do not leak (since clang-tblgen isn't long-lived, the old leak is probably acceptable, but it offended my senses nonetheless).

llvm-svn: 202989

The build was failing with:

  error C2664: 'std::atomic_int::atomic_int(const std::atomic_int &)' : cannot convert argument 1 from 'int' to 'const std::atomic_int &'

Apparently "std::atomic_int x(0)" doesn't work, but "std::atomic<int> x(0)"
does.

The following changes have been applied:

  - Removed 'align 4'. We can simplify this away, as it does not provide useful
    information in the example.
  - Use named instructions instead of '%0'. This is nicer, but more importantly
    this makes the IR valid. Before we had two assignments to %0 in a single
    example.
  - Add a missing branch instruction to make the loop structure clear.
  - Move one access into outer.for.body to make it not look that empty.
  - The statments that are only in the outer loop body should not reference the
    inner loop metadata, but only the outer loop. Only statements in both loops
    should reference both surrounding loops.
  - Rename the array indexes to make them all independent. Before there were
    identical array indexes in the inner and the outer loop. We want to
    avoid this special case as it may lead to confusion.

MSVC2013's standard library is too broken to understand this pattern.

This patch implements .set dsp directive and sets appropriate feature bits.This directive is a counterpart of -mattr=dsp command line option with the exception that it does not influence elf header flags. The usage example is gives in test file.

Use a scheme inspired by the Itanium ABI to properly implement the
mangling of lambdas.

N.B.  The incredibly astute observer will notice that we do not generate
external names that are identical, or even compatible with, MSVC.
This is fine because they don't generate names that they can use across
translation units.  Technically, we can generate any name we'd like so
long as that name wouldn't conflict with any other and would be stable
across translation units.

This fixes PR15512.

implementation already lives.

llvm-svn: 202961

already lived there and it is where it belongs -- this is the in-memory
debug location representation.

This is just cleanup -- Modules can actually cope with this, but that
doesn't make it right. After chatting with folks that have out-of-tree
stuff, going ahead and moving the rest of the headers seems preferable.

This will allow external callers of these functions to switch over time
rather than forcing a breaking change all a once. These particular
functions were determined by building clang/lld/lldb.

to ensure we don't mess up any of the overrides. Necessary for cleaning
up the Value use iterators and enabling range-based traversing of use
lists.
