.c file initializing an int4 from two int2s.

Unless the language mode is set to OpenCL, a vector initializer fusing multiple
smaller vectors into a larger vector is disallowed for extended vectors. 
Simple test case is attached, and fails with error:

"test.c:6:15: error: initializing 'int4' with an expression of incompatible
type"
