clang-format: Don't merge lines with comments.

Before:
  int f() { // comment return 42; }

After:
  int f() { // comment
    return 42;
  }

This fixes llvm.org/PR21769.

[libclang] Function templates can be 'overloaded' by return type, so encode the return type in the USR
and handle DependentNameType in order to be able to distinguish them.

[libclang] Reflect in USR generation that 'signed char' and 'unsigned char' can overload a 'char' in C++, by giving them distinct encodings.

[libclang] Use same USR encoding for 'class' as 'struct'.

'class' and 'struct' can be used interchangebly for forward references.
Use the same encoding otherwise we may get into a weird situation where the USR for the same
declaration is different based on whether the definition of the tag reference is visible or not.

[libclang] Encode location info for anonymous embedded tag decls.

Otherwise the USR will conflict with different embedded tag decls.

[libclang] Use same USR encoding for 'char' regardless of what the target considers the sign to be.

Should fix the clang-hexagon-elf bot.

clang-format: Support commas in lambda return types.

Before:
  auto next_pair = [](A * a) -> pair<A*, A*>{};

After:
  auto next_pair = [](A* a) -> pair<A*, A*>{};

InstrProf: Use LLVM's -instrprof pass for profiling

The logic for lowering profiling counters has been moved to an LLVM
pass. Emit the intrinsics rather than duplicating the whole pass in
clang.

Fix isInstantiated and isInTemplateInstantiation to not recreate the matchers on each call.

Summary:
Store the result matcher after the first call and reuse it later on.
Recreating the matchers just to use them once incurs in a lot of
unnecessary temporary memory allocations.
This change speeds up our clang-tidy benchmarks by ~2%.

clang-format: Indent correctly in conditional expressions after return.

This only applies when not aligning after the return itself (which is
commonly done for C++.

Before:
  return aaaaaaaaaa
      ? bbbbbbbbbb(
             bbbbbb)  // This is indented relative to aaaaaaaaaa.
      : b;

After:
  return aaaaaaaaaa
      ? bbbbbbbbbb(
            bbbbbb)

Handle possible TypoExprs in member initializers.

Includes a new test case since none of the existing tests were hitting
this code path.

Add a test for MS-ABI this adjustment for virtual calls to member operators.

They too were fixed by r223185, despite the commit message saying otherwise.
Add a test that makes sure they don't regress.

Revert "Driver: Objective-C should respect -fno-exceptions"

This reverts commit r223455.  It's been succesfully argued that
-fexceptions (at the driver level) is a misnomer and has little to do
with -fobjc-exceptions.
