Rollup merge of #110455 - durin42:tls-D148269-fix, r=nikic

tests: adapt for LLVM change 5b386b8

The above-mentioned change modified the output of thread-local.rs by changing some variable names. Rather than assume things get put in %0, we capture the variable so the test passes in both the old and new version.
