Since the lm32 is a 32 bit architecture, just return a 32 bit value which
is then converted to a 64 bit value.

The old milkymist.org domain just forwards to mm-labs.hk nowadays. I've
created a mirror of the documents.

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

man gcc:
Warn if in a loop with constant number of iterations the compiler
detects undefined behavior in some statement during one or more of
the iterations.
Milkymist pfpu has no jump instructions, so checking for MICROCODE_WORDS
instructions should have kept us in bounds of s->microcode, but i++
allowed one loop too many,
hw/misc/milkymist-pfpu.c: In function ‘pfpu_write’:
hw/misc/milkymist-pfpu.c:365:20: error: loop exit may only be reached after undefined behavior [-Werror=aggressive-loop-optimizations]
if (i++ >= MICROCODE_WORDS) {
^
hw/misc/milkymist-pfpu.c:167:14: note: possible undefined statement is here
uint32_t insn = s->microcode[pc];
^
The code can still access out of bounds, because it presumes that PC register
always begins at 0, and we allow writing to it.

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.
