Replace use of FLT_MAX in x86_64 zscal.c by isinf()
...
Commit def4996
fixed issues with inf and nan values in zscal,
but used FLT_MAX, where DBL_MAX or isinf() is more appropriate,
as FLT_MAX is for single precision only.
Using FLT_MAX caused test case failures in the LAPACK tests.
isinf() is consistent with the later fix 969601a1

Fix regression SAXPY when compiler with OpenXL compiler.
...
SAXPY built with OpenXL regresses when compared to SAXPY
built with gcc. OpenXL compiler doesn't know that the
SAXPY inner kernel assembly is a 64 element loop and
to it the remainder loop is the main loop. It vectorizes
and interleaves the remainder to be a 48 elements per
iteration loop. With a max of 63 iterations, a 48 element
loop is mostly not going to get executed, so the 1 element
scalar loop that is the remainder after that is probably
mostly what gets executed.
This can be fixed by adding a pragma, loop interleave_count(2)
which will result in 8 element loop.

Get the l2 cache size via environment variable on confidential VM
...
The CPUID(leaf:2 or leaf:0x80000006) is not supported on some confidential
VMs. As a result the get_l2_size() returns the default 512M which brings
performance issues.
Introduce the environment variable OPENBLAS_L2_SIZE provided by the user
to get the l2 cache size.
