Daniel Kiss ad40453fc4 [AArch64][compiler-rt] Strip PAC from the link register. 
-mbranch-protection protects the LR on the stack with PAC.
When the frames are walked the LR need to be cleared.
This inline assembly later will be replaced with a new builtin.

Test: build with  -DCMAKE_C_FLAGS="-mbranch-protection=standard".
