Subject: [PATCH 1/2] perf tests: Consolidate test__arch_unwind_sample declaration
Date:   Thu, 13 May 2021 12:46:13 -0500

There's no reason for making the test__arch_unwind_sample declaration per
arch. Currently that's done 2 different ways either with a declaration in
arch-tests.h or with an arch define. Unify all this with an unconditional
declaration in tests.h.

Note that the only thing really arch specific is getting the stack
pointer. I'm happy to refactor this further to just an arch function to
get the stack pointer reg.

Compiled on arm64 and x86.
