=== TEST SCRIPT
Changes for v3:
* Comment improvments for mips (phil).
* Patch 3 is new, rearranging some tcg/aarch64 helpers.
Changes for v2:
* Merge tcg_out_rev{16,32,64}, which perhaps solves the issue of
mnemonics vs actual opcodes, and also preps for Phil suggestion
of adding additional tcg opc
