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);

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;
