Revert: ARM: Enable use of relocation type tlsldo in debug info for tls data. There seems to be a new problem with the debug info in the test case. I'll have to investigate this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200737 91177308-0d34-0410-b5e6-96231b3b80d8 Kai Nacke 6 years ago
