Subject: [PATCH] tcg: Fix MAX_OPC_PARAM_IARGS

DEF_HELPER_FLAGS_5 was added some time ago without adjusting
MAX_OPC_PARAM_IARGS.

Fixing the definition becomes more important as QEMU is using
an increasing number of helper functions called with 5 arguments.

Add also a comment to avoid future problems when DEF_HELPER_FLAGS_6
will be added.
