Anastasia Stulova 960ff0810d [OpenCL][PR41727] Prevent ICE on global dtors
Pass NULL to pointer arg of __cxa_atexit if addr space
is not matching with its param. This doesn't align yet
with how dtors are generated that should be changed too.

Anastasia Stulova c25ea86d43 [Sema] Diagnose addr space mismatch while constructing objects
If we construct an object in some arbitrary non-default addr space
it should fail unless either:
- There is an implicit conversion from the address space to default
/generic address space.
- There is a matching ctor qualified with an address space that is
either exactly matching or convertible to the address space of an
object.

Johannes Doerfert 40107ce753 Introduce Value::stripPointerCastsSameRepresentation
This patch allows current users of Value::stripPointerCasts() to force
the result of the function to have the same representation as the value
it was called on. This is useful in various cases, e.g., (non-)null
checks.

In this patch only a single call site was adjusted to fix an existing
misuse that would cause nonnull where they may be wrong. Uses in
attribute deduction and other areas, e.g., D60047, are to be expected.

Anastasia Stulova e6cf6c78f8 [OpenCL] Make global ctor init function a kernel
We need to be able to enqueue internal function that initializes
global constructors on the host side. Therefore it has to be
converted to a kernel.

This change factors out common logic for adding kernel metadata
and moves it from CodeGenFunction to CodeGenModule in order to
make it accessible for the extra use case.

Anastasia Stulova 26e095e84f [OpenCL] Fix initialisation of this via pointer.
When the expression used to initialise 'this' has a pointer type,
check the address space of the pointee type instead of the pointer
type to decide whether an address space cast is required.
It is the pointee type that carries the address space qualifier.

Fixing PR41674.

Anastasia Stulova 6f7c536e08 [Sema] Change addr space diagnostics in casts to follow C++ style.
This change adds a new diagnostic for mismatching address spaces
to be used for C++ casts (only enabled in C style cast for now,
the rest will follow!).

The change extends C-style cast rules to account for address spaces.
It also adds a separate function for address space cast checking that
can be used to map from a separate address space cast operator
addrspace_cast (to be added as a follow up patch).

Note, that after this change clang will no longer allows arbitrary
address space conversions in reinterpret_casts because they can lead
to accidental errors. The implicit safe conversions would still be
allowed.

Anastasia Stulova 5cffa45401 [OpenCL] Allow address spaces as method qualifiers.
Methods can now be qualified with address spaces to prevent
undesirable conversions to generic or to provide custom 
implementation to be used if the object is located in certain
memory segments.

This commit extends parsing and standard C++ overloading to
work for an address space of a method (i.e. implicit 'this'
parameter).

Anastasia Stulova d1986d1b5a [OpenCL] Set generic addr space of 'this' in special class members.
Set address spaces of 'this' param correctly for implicit special
class members.

This also changes initialization conversion sequence to separate
address space conversion from other qualifiers in case of binding
reference to a temporary. In this case address space conversion  
should happen after the binding (unlike for other quals). This is
needed to materialize it correctly in the alloca address space.
