[PATCH] aarch64: Remove testing of saturation cumulative QC bit

[Kyrylo Tkachov]

Hi all,

Since we don't guarantee the ordering of the QC flag in FPSR in the saturation intrinsics, we shouldn't be testing for it.
I want to relax the flags for some of the builtins to enable more optimisation but that triggers the QC flag tests in advsimd-intrinsics.exp.
We don't implement the saturation flag access intrinsics in aarch64 anyway and we don't want to.

Tested on aarch64-none-elf and arm-none-eabi.

Pushing to master.
Thanks,
Kyrill
