cpu-exec.c: avoid AREG0 use

Browse source 
Make functions take a parameter for CPUState instead of relying
on global env. Pass CPUState pointer to TCG prologue, which moves
it to AREG0.

Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue
change.

Revert the hacks to avoid AREG0 use on Sparc hosts.

Move cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h.

Compile the file without HELPER_CFLAGS.
