The flag will perform instrumentation necessary to the fuzzing,
but will NOT link libLLVMFuzzer.a library.
Necessary when modifying CFLAGS for projects which may produce
executables as well as a fuzzable target.

Prior to this commit the
"(getContainingDC(DC) == CurContext && "The next DeclContext should be lexically contained in the current one."),"
assertion failure was triggered during semantic analysis of the dummy
tag declaration that was declared in another tag declaration because its
lexical context did not point to the outer tag decl.

We do not meaningfully track object const-ness of Objective-C object

Such implicitly declared functions behave as if the enclosing block
contained the declaration extern int name() (C90, 6.3.3.2 Function calls),
thus their names should have block scope (C90, 6.1.2.1 Scope of identifiers).

The original patch was an improvement to IR ValueTracking on non-negative
integers. It has been checked in to trunk (D18777, r284022). But was disabled by
default due to performance regressions.
Perf impact has improved. The patch would be enabled by default.

This is an improvement over always using byval for
structs.
This will use registers until ~16 are used, and then
switch back to byval. This needs more work, since I'm
not sure it ever really makes sense to use byval. If
the register limit is exceeded, the arguments still
end up passed on the stack, but with a different ABI.
It also may make sense to base this on number of
registers used for non-struct arguments, rather than
just arguments that appear first in the argument list.

If the host code is compiled with the debug info, while the target

C++14 added user-defined literal support for complex numbers so that you
can write something like "complex<double> val = 2i". However, there is
an existing GNU extension supporting this syntax and interpreting the
result as a _Complex type.
This changes parsing so that such literals are interpreted in terms of
C++14's operators if an overload is present but otherwise falls back to
the original GNU extension.
(We now have more robust diagnostics for implicit conversions so the
libc++ test that caused the original revert still passes).

It was timing out on this test, but for reasons unrelated to the
specific bug it was testing for. Randomly breaking in gdb with `clang
-target i686-windows -fmsc-version=1700` reveals *many* frames from
MicrosoftCXXNameMangler. So, it would seem that some caching is needed
there, as well...
Fingers crossed that specifying a triple is sufficient to work around
this.

This is a follow-up to r310436 with actual functional changes. Please

Do not discard invalid Decl when searching for the operator delete function.
The lookup for this function always expects to find a result, so sometimes the
invalid Decl is the only choice possible. This fixes PR34109.

Converting a _Complex type to a real one simply discards the imaginary part.
This can easily lead to loss of information so for safety (and GCC
compatibility) this patch disallows that when the conversion would be implicit.
The one exception is bool, which actually compares both real and imaginary
parts and so is safe.

Previously we limited ourselves to only emitting nested classes, but we
