[PPC] Linker fails on -fstack-protector
...an offset from an address space.

I also found a similar case - getSafeStackPointerLocation(). On X86 it's
implemented in terms of address space (similar to getStackCooikeLocation),
but on AArch64 it's implemented in terms of a target specific
AArch64ISD::THREAD_POINTER and Intrinsic::aarch64_thread_pointer.
To make the fix least surprising, I can either do:
1) Create PPCISD::THREAD_POINTER and Intrinsic::ppc_thread_pointer and do
similar things aarch64 does; or
2) Don't create PPCISD::THREAD_POINTER, but directly calls
llvm.read_register intrinsic in ppc's getStackCookieLocation(). This is t...

[PPC] Linker fails on -fstack-protector
I found a bit weird to use address space for this, since the offset of
getting stack_guard in TCB is, unfortunately, negative:

In my understanding an address space is referring to a segment register
(-on powerpc 32bit; or SLB entry on powerpc 64bit?) with a non-negative
offset value, so that it's actually accessing
