protze@itc.rwth-aachen.de 90e4ebdce5 [OpenMP][OMPT] fix reduction test for 32-bit x86
Fixes [[ https://bugs.llvm.org/show_bug.cgi?id=44733 | TEST 'libomp :: ompt/synchronization/reduction/tree_reduce.c' FAILED on 32-bit x86 ]]

For 32-bit we need at least 3 variables to avoid atomic reduction to be
choosen by runtime function `__kmp_determine_reduction_method`.
This patch adds reduction variables to the testcase.

Aaron Puchert b29c7fdb61 [OpenMP] Remove -Wl,-fini=__kmp_internal_end_fini
Summary:
The termination function duplicated the functionality of the
__attribute((destructor))-annotated function __kmp_internal_end_fini,
and we have no indication that this doesn't work.

The function might cause issues with link-time optimization turned on:
until very recently, none of the usual linkers was reporting functions
named in -Wl,-fini as used to the LTO plugin, so it might be dropped.
If the function is dropped, -Wl,-fini=__kmp_internal_end_fini doesn't
do what we want: with ld.bfd and lld it drops the FINI attribute from
.dynamic and with gold we get FINI = 0x0, which leads to a crash on
cleanup. This can be reproduced by building with

    -DLLVM_ENABLE_PROJECTS="clang;openmp" \
    -DLLVM_ENABLE_LTO=Thin \
    -DLLVM_USE_LINKER=gold

The issue in lld has been fixed in f95273f75a, but gold remains without
fix so far.

Fixes PR43927.

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.
