clang-p2996/llvm/test/CodeGen/AArch64/fptrunc.ll
Sander de Smalen 61510b51c3 Revert "[AArch64] Enable subreg liveness tracking by default." 
This reverts commit 9c319d5bb4.

Some issues were discovered with the bootstrap builds, which
seem like they were caused by this commit. I'm reverting to investigate.
