The VSX TCG code is using _i64 types mixed wiht _tl types. While this
is correct for 64-bit targets, this breaks the compilation with 32-bit
targets and --enable-debug-tcg.

This patch fixes that by always using the correct type. Note that we can
probably do better for the load/stores using the new load/store TCG
instructions, but that would need changes to other places of the code,
while this patch intents to be a bug fix patch only.

I've sent a similar patch last week. Would you mind to review that one and maybe ack it?

Thanks a lot!
