Amy Huang a85f5efd95 Add support for the MS qualifiers __ptr32, __ptr64, __sptr, __uptr.
Summary:
This adds parsing of the qualifiers __ptr32, __ptr64, __sptr, and __uptr and
lowers them to the corresponding address space pointer for 32-bit and 64-bit pointers.
(32/64-bit pointers added in https://reviews.llvm.org/D69639)

A large part of this patch is making these pointers ignore the address space
when doing things like overloading and casting.

Yaxun Liu b7318e02c1 [OpenCL] Add LangAS::opencl_private to represent private address space in AST
Currently Clang uses default address space (0) to represent private address space for OpenCL
in AST. There are two issues with this:

Multiple address spaces including private address space cannot be diagnosed.
There is no mangling for default address space. For example, if private int* is emitted as
i32 addrspace(5)* in IR. It is supposed to be mangled as PUAS5i but it is mangled as
Pi instead.

This patch attempts to represent OpenCL private address space explicitly in AST. It adds
a new enum LangAS::opencl_private and adds it to the variable types which are implicitly
private:

automatic variables without address space qualifier

function parameter

pointee type without address space qualifier (OpenCL 1.2 and below)

Andrew Gozillon 25b16572e9 Dependent Address Space Support Test Fix
Modifying a non-type template integer arguement that is causing errors 
in some builds as it's too large for 32-bit longs. This hopefully (and 
seems to when testing) should fix all of the build bot errors relating 
to this test. I also modified the name of the function call to be more 
apt.

Andrew Gozillon 0cd141ba9d Dependent Address Space Support Test File
Adding regression test for Dependent Address Spaces in relation to
https://reviews.llvm.org/D33666 I forgot to svn add the test file 
before commiting the prior changes. I appologies.
