Do not duplicate identical stack safety test for RISCV

11–12

This is a bit dodgy as this isn't a data layout used by RISC-V, but hard to avoid without D141060 unless you want to duplicate the test or put the data layout as an argument to opt

For what it's worth, that is also the data layout that is used in the deleted llvm/test/Instrumentation/HWAddressSanitizer/RISCV/stack-safety-analysis.ll.
