Make SVE-enabled ARM64 targets in DYNAMIC_ARCH builds depend on a relatively recent compiler

Remove prefetches from SVE kernels

Fix uninitialized variables on quick return paths of ?LARR? (Reference-LAPACK 775)

GH workflow: ensure libtinfo is available for Linux/flang

Add sscal.c + microkernels for Haswell, Zen, Skylake and newer.

Copy NO_WARMUP preset from Makefile.rule to CMAKE to fix startup delays

This is a precursor to enabling the SVE kernels for Arm(R) Neoverse(TM)
V1 which has 256-bit SVE. Testing revealed that the SVE kernel was
actually worse in some cases than the existing kernel which seemed odd -
removing these prefetches the underlying architecture seems to do a better job

Fix INTERFACE64 option handling in gmake builds on riscv and loongarch

Add -lm on any arm/arm64 BSD, not just FreeBSD

Patch for Intel Fortran compiler

Fix C function signatures in LAPACKE headers and f2c-generated LAPACK C files

This PR patches the f_check scripts to detect the ifort compiler. With
out this, the value of F_COMPILER is G77 which causes the link phase to
use icc rather than ifort, resulting in missing libifcore.

Fix stride in shortcut path of C/ZSYR for small N

Travis CI: Add a DYNAMIC_ARCH build on Neoverse using older gcc8

Remove SVE from Arm(R) Neoverse(TM) N1 CPU in Makefile

I incorrectly added `+sve` to the Neoverse(TM) N1 CPUs GCC parameters,
which doesn't support SVE - this results in failed builds when using a
compiler that doesn't support `-mtune=neoverse-n1` which appears to hide
the mistake.

Unlike [dcz]scal, sscal still used the original GotoBLAS SSE code from scal_sse.S.
This code follows dscal as closely as possible, except for the inc_x > 1 code
for which a plain C loop is used much like the one in cscal.c, instead of an
adaptation of the SSE2 asm code of dscal.c (I tried but the performance wasn't
better than the plain C loop).
