Remove unused CONFIG_TCG_PASS_AREG0 and dead code

Browse source 
Now that CONFIG_TCG_PASS_AREG0 is enabled for all targets,
remove dead code and support for !CONFIG_TCG_PASS_AREG0 case.

Remove dyngen-exec.h and all references to it. Although included by
hw/spapr_hcall.c, it does not seem to use it.

Remove unused HELPER_CFLAGS.
