target-sparc: Add MMU_PHYS_IDX
It's handy to have a mmu idx for physical addresses, so
that mmu disabled and physical access asis can use the
same path as normal accesses.

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 helper_ldf_asi, helper_stf_asi
We've now implemented all fp asis inline, except for the no-fault
memory reads. The latter can be passed directly to helper_ld_asi.

target-sparc: Pass TCGMemOp constants to helper_ld/st_asi
Reduces the argument count for helper_ld_asi; do helper_st_asi
for consistency.

Fix confusing argument names in some common functions
There are functions tlb_fill(), cpu_unaligned_access() and
do_unaligned_access() that are called with access type and mmu index
arguments. But these arguments are named 'is_write' and 'is_user' in their
declarations. The patches fix the arguments to avoid a confusion.

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.

This commit was created with scripts/clean-includes.
