Subject: AMDGPU: Cleanup test
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ba1978624ffe2f475981136862142402e066d5e9;p=oota-llvm.git

AMDGPU: Cleanup test

Run instnamer on it, and rename check prefix.

This is in preparation for adding new testcases to cover
bugs on other subtargets.
