target-sparc: Introduce cpu_raise_exception_ra
Several helpers call helper_raise_exception directly, which requires
in turn that their callers have performed save_state. The new function
allows a TCG return address to be passed in so that we can restore
PC + NPC + flags data from that.

This fixes a bug in the usage of helper_check_align, whose callers had
not been calling save_state. It fixes another bug in which the divide
helpers used GETPC at a level other than the direct callee from TCG.

This allows the translator to avoid save_state prior to SAVE, RESTORE,
and FLUSHW instructions.

target-sparc: Remove softint as a TCG global
The global is only ever read for one insn; we can just as well
use a load from env instead and generate the same code. This
also allows us to indicate the the associated helpers do not
touch TCG globals.

cpu: move exec-all.h inclusion out of cpu.h
exec-all.h contains TCG-specific definitions. It is not needed outside
TCG-specific files such as translate.c, exec.c or *helper.c.

One generic function had snuck into include/exec/exec-all.h; move it to
include/qom/cpu.h.

sparc: Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
