Work around excessive LAPACK test failures on Skylake-X
...
Something in the plain C parts of x86_64 cscal.c and zscal.c appears to be miscompiled by both gfortran9 and ifort when compiling for skylakex-avx512, even when the optimized Haswell microkernel is not in use.

...
As discussed on the original PR #2329 , the "Apple Clang 11.0.3" that appears to be based the same LLVM release produces the same miscompilation of this file.

Fix implementation of iamax_sse.S as reported in #2116 .

The was a typo in iamax_sse.S where one of the comparison
was cmpeqps instead of cmpeqss. That misdetected index
for sequences where the minimum value was 0.

Fix inline asm in dscal: mark x, x1 as clobbered. Fixes #2408
...
The leaq instructions in dscal_kernel_inc_8 modify x and x1 so they
must be declared as input/output constraints, otherwise the compiler
may assume the corresponding registers are not modified.
