Merge #20479: Fix QPainter non-determinism on macOS (0.21 backport)
ab23a83400d5ad13137ce0f9697a51f0b70e9d29 Fix QPainter non-determinism on macOS (Andrew Chow)
Pull request description:
Aplies a patch to Qt that fixes the non-determinism by modifying Qt. The
source of the non-determinism is how LLVM 8 optimizes qt_intersect_spans
when compiling. The particular optimization that seems to be causing the
problems is that a temp variable is being added for spans->y. For some
reason, when it does this, it chooses different instructions to use when
making that variable. We bypass this problem by patching
qt_intersect_spans to always make and use this local variable.
