Switch back to non-ARM ABI for C++ guard variables under PNaCl
My previous change set IsARM=true for PNaCl in ItaniumCXXABI.cpp.
This gives us ARM-style representation of method pointers, which we
want, and ARM-style usage of guard variables, which we don't
necessarily want.
Switch the latter back so that the guard variable is tested via "load
i8 and compare with zero" rather than a "load i32 and test the bottom
bit". This should make the Clang-generated code match with how
libstdc++ is using the guard variable.
This makes the code match the patch I sent upstream (which hasn't been
committed yet).
