  Log Message:
  [clang][ARM] re-use arm::isHardTPSupported for hardware TLS check

This conditional check for -mstack-protector-guard=tls got out of sync
with the conditional check for -mtp=cp15 by me in D114116, because I
forgot about the similar check added in D113026.

Re-use the code in arm::isHardTPSupported so that these aren't out of

Interestingly, our CI reported this when testing
-mstack-protector-guard=tls; it was only reproducible with Debian's LLVM
and not upstream LLVM due to this out of tree patch:
