Add printing of __private address space to TypePrinter to allow
it appears in diagnostics and AST dumps as all other language
addr spaces.

Differential Revision: https://reviews.llvm.org/D71272
The original commit failed to handle "shift assign" (<<=), which
broke the test mentioned in r228406. This is now fixed and the
test added to the lit tests under SemaOpenCL.
*** Original commit message from r228382 ***
OpenCL: handle shift operator with vector operands
Introduce a number of checks:
1. If LHS is a scalar, then RHS cannot be a vector.
2. Operands must be of integer type.
3. If both are vectors, then the number of elements must match.
Relax the requirement for "usual arithmetic conversions":
When LHS is a vector, a scalar RHS can simply be expanded into a
vector; OpenCL does not require that its rank be lower than the LHS.
For example, the following code is not an error even if the implicit
type of the constant literal is "int".
char2 foo(char2 v) { return v << 1; }
Consolidate existing tests under CodeGenOpenCL, and add more tests
under SemaOpenCL.

This reverts commit r228382.
This breaks the following case: Reported by Jeroen Ketema:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20150202/122961.html
typedef __attribute__((ext_vector_type(3))) char char3;
void foo() {
char3 v = {1,1,1};
char3 w = {1,2,3};
w <<= v;
}
If I compile with:
clang -x cl file.c
Then an error is produced:
file.c:10:5: error: expression is not assignable
w <<= v;
~ ^
1 error generated.

It had program scope variables that were not in the constant address space,
make them to be function scope variables instead.
Also move the test to the SemaOpenCL directory.
