cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.Explicitly zero them on reset since they were located beforebreakpoints.
Pass PowerPCCPU to kvmppc_handle_halt().

Sparc: fix coding style in helper.c
Before the next patch, fix coding style of the areas affected.
Sparc: avoid AREG0 for division op helpers
Make [su]div{,cc} helpers take a parameter for CPUState insteadof relying on global env. Move the functions to helper.c.
Sparc: avoid AREG0 for raise_exception and helper_debug
Make raise_exception() and helper_debug() take a parameter forCPUState instead of relying on global env. Move the functionsto helper.c.
Sparc: move trivial functions from op_helper.c
These functions don't need access to CPUState or already pass it,so relocating them from op_helper.c to helper.c and int64_helper.cis trivial.
Sparc: split helper.c
Move CPU init to cpu_init.c and interrupt handling to int32_helper.cfor Sparc32 and int64_helper.c for Sparc64.
