Sam McCall f1f6e0fc24 [CodeComplete] Improve overload handling for C++ qualified and ref-qualified methods.
Summary:
- when a method is not available because of the target value kind (e.g. an &&
  method on a Foo& variable), then don't offer it.
- when a method is effectively shadowed by another method from the same class
  with a) an identical argument list and b) superior qualifiers, then don't
  offer it.

Ilya Biryukov 30977fc3a9 [CodeComplete] Include more text into typed chunks of pattern completions
Summary:
To allow filtering on any of the words in the editors.
In particular, the following completions were changed:
    - 'using namespace <#name#>'
      Typed text before: 'using', after: 'using namespace'.
    - 'else if (#<condition#>)'
      Before: 'else', after: 'else if'.
    - 'using typename <#qualifier#>::<#name#>'
      Before: 'using', after: 'using typename'.

Ilya Biryukov 1a44584588 [CodeComplete] Add a bit more whitespace to completed patterns
Summary:
E.g. we now turn `while(<#cond#>){` into `while (<#cond#>) {`

This slightly improves the final output. Should not affect clients that
format the result on their own.

Ilya Biryukov 49e432d030 [CodeComplete] Consistently break after '{' in multi-line patterns
Summary:
Completion can return multi-line patterns in some cases, e.g.

    for (<#init#>; <#cond#>; <#inc#>) {
    <#body#>
    }

However, most patterns break the line only before closing brace,
resulting in code like:

    namespace <#name#> { <#decls#>
    }

While some (e.g. the 'for' example above) are breaking lines after the
opening brace too.

This change ensures all patterns consistently break after the opening
brace, this leads to nicer UX when using those in an actual editor.

Ilya Biryukov cabab29af2 [CodeComplete] Filter override completions by function name
Summary:
We put only part of the signature starting with a function name into "typed text"
chunks now, previously the whole signature was "typed text".

This leads to meaningful fuzzy match scores, giving better signals to
compare with other completion items.

Ideally, we would not display the result type to the user, but that requires adding
a new kind of completion chunk.

David Goldman 3e804d2581 Support framework import/include auto-completion
Frameworks filesystem representations:
  UIKit.framework/Headers/%header%

Framework import format:
  #import <UIKit/%header%>

Thus the completion code must map the input format of <UIKit/> to
the path of UIKit.framework/Headers as well as strip the
".framework" suffix when auto-completing the framework name.

Nemanja Ivanovic db64e7e9fa [NFC] Explicitly add -std=c++14 option to tests that rely on the C++14 default
When Clang/LLVM is built with the CLANG_DEFAULT_STD_CXX CMake macro that sets
the default standard to something other than C++14, there are a number of lit
tests that fail as they rely on the C++14 default.
This patch just adds the language standard option explicitly to such test cases.

Aaron Ballman fb6deeb984 Refactor the way we handle diagnosing unused expression results.
Rather than sprinkle calls to DiagnoseUnusedExprResult() around in places where we want diagnostics, we now diagnose unused expression statements and full expressions in a more generic way when acting on the final expression statement. This results in more appropriate diagnostics for [[nodiscard]] where we were previously lacking them, such as when the body of a for loop is not a compound statement.

This patch fixes PR39837.

Ilya Biryukov 143a9e0b12 [CodeComplete] Fix assertion failure
Summary:
...that fires when running completion inside an argument of
UnresolvedMemberExpr (see the added test).

The assertion that fires is from Sema::TryObjectArgumentInitialization:

    assert(FromClassification.isLValue());

This happens because Sema::AddFunctionCandidates does not account for
object types which are pointers. It ends up classifying them incorrectly.
All usages of the function outside code completion are used to run
overload resolution for operators. In those cases the object type being
passed is always a non-pointer type, so it's not surprising the function
did not expect a pointer in the object argument.

However, code completion reuses the same function and calls it with the
object argument coming from UnresolvedMemberExpr, which can be a pointer
if the member expr is an arrow ('->') access.

Extending AddFunctionCandidates to allow pointer object types does not
seem too crazy since all the functions down the call chain can properly
handle pointer object types if we properly classify the object argument
as an l-value, i.e. the classification of the implicitly dereferenced
pointer.
