2689133805 Simplifying the OpenCL image attribute. It does not need a semantic integer parameter because the required information is encoded in the spelling. Added an appropriate subject to the attribute, and simplified the semantic checking (which will likely be expanded upon in a future patch). Also, removed the GNU spelling since it was unsupported in the first place.

49b3841398 The comparison of two vectors should return a signed result. hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also 
changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.

766bcc27dc In OpenCL, conversions between different vector types are disallowed 
OpenCL 6.2.1 says: "Implicit conversions between built-in vector data types are
disallowed."  OpenCL 6.2.2 says: "Explicit casts between vector types are not
legal."  For example:

uint4 u = (uint4)(1);
int4 i = u; // invalid implicit conversion
int4 e = (int4)u; // invalid explicit conversion

0a3a22fe66 In the OpenCL mode, the AltiVec mode must be off and checks must be strict 
OpenCL is different from AltiVec in the way it supports vector literals.  OpenCL
is strict with regards to semantic checks.  For example, implicit conversions
and explicit casts between vectors of different types are disallowed.
