Anastasia Stulova 782d5f43ca [OpenCL] Improve diagnostics of address spaces for variables in function 
- Prevent local variables to be declared in global AS
 - Diagnose AS of local variables with an extern storage class
   as if they would be in a program scope

Anastasia Stulova bcea69669f [OpenCL 2.0] Enable program scope variables, Section 6.5.1. 
- Remove virtual SC_OpenCLWorkGroupLocal storage type specifier
as it conflicts with static local variables now and prevents
diagnosing static local address space variables correctly.

 - Allow static local and global variables (OpenCL2.0 s6.8 and s6.5.1).

 - Improve diagnostics of allowed ASes for variables in different scopes:
(i) Global or static local variables have to be in global
or constant ASes (OpenCL1.2 s6.5, OpenCL2.0 s6.5.1);
(ii) Non-kernel function variables can't be declared in local
or constant ASes (OpenCL1.1 s6.5.2 and s6.5.3).

Joey Gouly 130a91e494 Fix a non-conformant OpenCL test case. 
Program scope variables must be declared in the constant address space
and are required to be initialized.

Tanya Lattner 4fdce3faa8 Extend the support for cl-std to include 1.2. 
Add error checking for the static qualifier which is now allowed in certain situations for OpenCL 1.2. Use the CL version to turn on this feature.
Added test case for 1.2 static storage class feature.
