Tom Stellard 70f13dba15 R600/SI: Use -verify-machineinstrs for most tests 
We can't enable the verifier for tests with SI_IF and SI_ELSE, because
these instructions are always followed by a COPY which copies their
result to the next basic block.  This violates the machine verifier's
rule that non-terminators can not folow terminators.

Tom Stellard 9fa1791a1b R600/SI: Convert v16i8 resource descriptors to i128 
Now that compute support is better on SI, we can't continue using v16i8
for descriptors since this is also a legal type in OpenCL.

This patch fixes numerous hangs with the piglit OpenCL test and since
we now use a target specific DAG node for LOAD_CONSTANT with the
correct MemOperandFlags, this should also fix:

Tom Stellard b81df0c7ea R600/SI: Use i8 types for resource descriptors in tests 
We switched from i32 to i8 types a while ago and the tests were never
updated.
