Subject: Remove unused class variables and update all callers/uses from
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=07980e9ade2eec9caf90180c131a2e4c75335456

Remove unused class variables and update all callers/uses from
the HexagonSplitTFRCondSet pass. Use the subtarget off the machine
function at the same time.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227878 91177308-0d34-0410-b5e6-96231b3b80d8
