01d05266f9 Fix external symbol printing in the AsmPrinter. Tell the ISel that we 
don't support things like memcpy directly.  This allows a handful of the
Shootout programs to work, yay!

f7fe494c19 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.  :-(

7a823bd01f Fix a problem where the PPC backend lost track of the fact that it had 
to save and restore the LR register on entry and exit of a leaf function
that needed to access globals or the constant pool.  This should hopefully
fix oscar from sending the PPC tester spinning out of control.

8399e02a2c 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;
}
