  Log Message:
  -----------
  [PowerPC][ISelLowering] Support -mstack-protector-guard=tls (#110928)

Add support for using a thread-local variable with a specified offset
for holding the stack guard canary value. This supports both 32- and 64-
bit PowerPC targets.

This mirrors changes from #108942 but targeting PowerPC instead of
RISCV. Because both of these PRs modify the same driver functions, this
series is stack on top of the RISC-V one.
