Benjamin Kramer 9a9efbafa7 [Modules] Wrap the main ModuleManager visitor in a function_ref.
Avoids the awkward passing of an opaque void *UserData argument. No

David Majnemer 6cd35912c0 [CodeGen] Don't UBSan-ize the argument to __builtin_frame_address
__builtin_frame_address requires its argument to be a constant
expression which already implies that it cannot have undefined behavior.
However, we used EmitScalarExpr to emit the argument causing UBSan to
try to check for overflow.

Instead, use the constant expression emission system.

This fixes PR24256.

Akira Hatanaka 4e3c86fe99 [AArch64] Pass subtarget feature "+reserve-x18" instead of passing backend
option "-aarch64-reserve-x18".

This change is needed since backend options do not make it to the backend
when doing LTO and are not capable of changing the behavior of code-gen
passes on a per-function basis.

Change `getOrCreateLimitedType()` to return a `DICompositeType` and
remove the casts from its callers.  Inside, I've strengthened a `cast`
from `DICompositeTypeBase`, but the casts in the callers already prove
that this is safe.  There should be no functionality change here.

Argyrios Kyrtzidis f0917ab7c1 [code-completion] Strip outer nullability annotations when completing method implementations.
The outer nullability is transferred from the declaration to the implementation so including them is redundant.
The inner ones are not transferred so they are kept to match the exact types. When we transfer the inner ones as well
adding them in the implementation will become redundant and we should strip those as well.

Piotr Padlewski a68a78751f Generating available_externally vtables for outline virtual functions
Generating available_externally vtables for optimizations purposes.
Unfortunatelly ItaniumABI doesn't guarantee that we will be able to
refer to virtual inline method by name.
But when we don't have any inline virtual methods, and key function is
not defined in this TU, we can generate that there will be vtable and
mark it as available_externally.

This is patch will help devirtualize better.

Renato Golin 830f0c4c46 [Compiler-RT] Remove dependency on libgcc_s/eh
Currently, for --rtlib=compiler-rt on GNU systems, we're assuming
that one has libgcc_s and libgcc_eh as low-level libraries, which
when used in conjunction with -lunwind or -lc++abi, breaks that
assumption.

My original fix was wrong, and this patch reverts it to prepare for
a new flag to choose the unwinder/C++ libraries. For the time being,
people can use "-lgcc_s -lgcc_eh" or "-lunwind -lc++abi" or any
combination they need explicitly.

David Majnemer 51fd8a020b [MS Compat] Allow _Atomic(Type) and 'struct _Atomic' to coexist
MSVC 2013 ships, as part of its STL implementation, a class named
'_Atomic'.  This is unfortunate because this keyword is in conflict with
the C11 keyword with the same name.  Our solution was to disable this
keyword when targeting MSVC 2013 and reenable it for 2015.

However, this makes it impossible for clang's headers to make use of
_Atomic.  This is problematic in the case of libc++ as it makes heavy
use of this keyword.

Let the keywordness of _Atomic float under certain circumstances:
the body of a class named _Atomic, or a class with a base specifier
named _Atomic, will not have the keyword variant of _Atomic for the
duration of the class body.  This is sufficient to allow us to correctly
handle _Atomic in the STL while permitting us to use _Atomic as a
keyword everywhere else.
