    Fix clang stack alignment issues · 7737e6ad
    Henrik Gramner authored
    Clang emits aligned AVX stores for things like zeroing stack-allocated
    variables when using -mavx even with -fno-tree-vectorize set which can
    result in crashes if this occurs before we've realigned the stack.
    Previously we only ensured that the stack was realigned before calling
    assembly functions that accesses stack-allocated buffers but this is
    not sufficient. Fix the issue by changing the stack realignment to
    instead occur immediately in all CLI, API and thread entry points.
