Further improvements to memory.c. ( #1625 )
...
- Compiler TLS is now used only used when the compiler supports it
- If compiler TLS is unsupported, we use platform-specific TLS
- Only one variable (an index) is now in TLS
- We only access TLS once per alloc, and never when freeing
- Allocation / release info is now stored within the allocation itself, by
over-allocating; this saves having external structures do the bookkeeping, and
reduces some of the redundant data that was being stored (such as addresses)
- We never hit the alloc lock when not using SMP or when using OpenMP (that was
my fault)
- Now that there are fewer tracking structures I think this is a bit easier to
read than before

On x86-64, make MB/WMB compiler barriers
...
Whie on x86(64) one does not normally need full memory barriers, it's
good practice to at least use compiler barriers for places where on other
architectures memory barriers are used; this prevents the compiler
from over-optimizing.

Add missing barriers in gemm scheduler

a few places in the gemm scheduler code were missing barriers;
the code likely worked OK due to heavy use of volatile / _Atomic
but there's no reason to get this incorrect
