Changed clobbered registers to R10 <https://reviews.llvm.org/source/svn-test-suite/> and R11 <https://reviews.llvm.org/source/libunwind/> because PLT resolution clobbers them. Also changed in implementation to use R11 <https://reviews.llvm.org/source/libunwind/> instead of RCX, which saves a push/pop.
