Do not lower malloc's to pass "sizeof" expressions like this:
...
ltmp_0_7 = malloc(((unsigned )(&(((signed char (*)[784])/*NULL*/0)[1u]))));
Instead, just emit the literal constant, like this:
ltmp_0_7 = malloc(784u);
This works around a bug in ICC 8.1 compiling the CBE generated code. :-(

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;

Small performance improvement in generated C code:
...
Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.
This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.
