This patch introduces acle_sqrt.c in the AArch64 testsuite, verifying
that the new __sqrt and __sqrtf intrinsics emit the expected fsqrt
instructions for double and float arguments.
Coverage for new intrinsics ensures that __sqrt and __sqrtf are
correctly expanded to hardware instructions and do not fall back to
library calls, regardless of optimization levels.
