Roland McGrath 2b0e6fe2e2 [Fuchsia] Remove aarch64-fuchsia target-specific -mcmodel=kernel
Under --target=aarch64-fuchsia, -mcmodel=kernel has the effect of
(the default) -mcmodel=small plus -mtp=el1 (which did not exist when
this behavior was added). Fuchsia's kernel now uses -mtp=el1
directly instead of -mcmodel=kernel, so remove this special support.

Petr Hosek 9eb0a1e09b [AArch64][Fuchsia] Allow -mcmodel=kernel for --target=aarch64-fuchsia
This mode is just like -mcmodel=small except that it moves the
thread pointer from TPIDR_EL0 to TPIDR_EL1.

Petr Hosek a7d5916308 [Fuchsia] Use thread-pointer ABI slots for stack-protector and safe-stack
The Fuchsia ABI defines slots from the thread pointer where the
stack-guard value for stack-protector, and the unsafe stack pointer
for safe-stack, are stored. This parallels the Android ABI support.

Evgeniy Stepanov dde29e2799 Faster stack-protector for Android/AArch64.
Bionic has a defined thread-local location for the stack protector
cookie. Emit a direct load instead of going through __stack_chk_guard.
