This comes up with ARMv7s, where the C++ toolchain handles it as a separate architecture and may end up compiling the code in a substantially different way, while the LLInt doesn't care. The fix for https://bugs.webkit.org/show_bug.cgi?id=90098 causes the offlineasm's knowledge of ARMv7s to be dropped, since it assumes that if the offsets are the same then the configuration is the same. That's just plain wrong, since it's the configuration index (identifying the combination of settings flags) that should be uniq'd, not the offsets.
