Richard Henderson 42a268c241 tcg: Change translator-side labels to a pointer 
This is improved type checking for the translators -- it's no longer
possible to accidentally swap arguments to the branch functions.

Note that the code generating backends still manipulate labels as int.

With notable exceptions, the scope of the change is just a few lines
for each target, so it's not worth building extra machinery to do this
change in per-target increments.

Peter Maydell ec53b45bcd exec.c: Drop TARGET_HAS_ICE define and checks 
The TARGET_HAS_ICE #define is intended to indicate whether a target-*
guest CPU implementation supports the breakpoint handling. However,
all our guest CPUs have that support (the only two which do not
define TARGET_HAS_ICE are unicore32 and openrisc, and in both those
cases the bp support is present and the lack of the #define is just
a bug). So remove the #define entirely: all new guest CPU support
should include breakpoint handling as part of the basic implementation.

Paolo Bonzini f08b617018 softmmu: introduce cpu_ldst.h 
This will collect all load and store helpers soon.  For now
it is just a replacement for softmmu_exec.h, which this patch
stops including directly, but we also include it where this will
be necessary in order to simplify the next patch.

Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h.  This
minimizes the files that must be rebuilt when changing the macros

Juan Quintela 35d08458a9 savevm: Remove all the unneeded version_minimum_id_old (rest) 
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Richard Henderson 06ef8604e9 target-alpha: Remove cpu_unique, cpu_sysval, cpu_usp 
Technically, these variables could have been referenced both via
offsets from env and as TCG registers, which would be illegal.
Of course, that could only be done from PALcode, and ours doesn't
do that.

But honestly, these are used infrequently enough that they don't
really need to be TCG registers.  We wind up with exactly the same
code if we follow the letter of the law and issue explicit ld/st.
