Jonas Hahnfeld 673e5476a8 [OpenMP] Change initialization of __kmp_global
There's no need to initialize variables with static storage duration
because they're implicitly initialized to zero. See
https://en.cppreference.com/w/c/language/initialization#Implicit_initialization

I think that's already relied upon because the supplied 0 only sets
'kmp_time_global_t g_time;' in 'struct kmp_base_global'. The other fields
are not set in the code, but implicitly initialized by the compiler.

on these architectures, so I don't want to change the code just
because it looks right :)

The current logic behind this assumes that the L2 cache is always at deeper

for all packages (and the packages are at deeper level than L2 cache) the whole of
the further topology discovery fails to find any computational units resulting in
following assertion:

valid, and it's not clear whether it's supposed to mean uxtw or uxtx.

It doesn't matter which instruction we use here, since the high
