Assorted fixes:
...
* Stop being pessimistic about output register allocation
* Start to handle function descriptors: compute target GPs and so on
when doing indirect calls etc. Not there yet, though. For the moment,
we try to use _indirect_ branches wherever possible, to stress test
function descriptors.
* FP divide-by-zero should work now
* add varargs (it doesn't work, though)
At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)

Fix volatile load/store of pointers. Consider this testcase:
...
void %test(int** %P) {
%A = volatile load int** %P
ret void
}
void %test2(int*** %Q) {
%P = load int*** %Q
volatile store int** %P, int*** %Q
ret void
}
instead of emitting:
void test(int **l1_P) {
int *l2_A;
l2_A = (int **((volatile int **)l1_P));
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((volatile int ***)l2_Q) = l1_P;
return;
}
... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):
void test(int **l1_P) {
int *l3_A;
l3_A = *((int * volatile*)l1_P);
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((int ** volatile*)l2_Q) = l1_P;
return;

so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
