b79cdb101f print encodings like this: 
pslld	69, %mm3                ## encoding: [0x0f,0xf2,0x1c,0x25,0x45,0x00,0x00,0x00]

instead of like this:
	pslld	69, %mm3                ## encoding: [0x0f,0xf2,0x1c,0x25,0x45,0000,0000,0000]

670458b3be Teach SimplifyCFG about magic pointer constants. 
Weird code sometimes uses pointer constants other than null. This patch
teaches SimplifyCFG to build switch instructions in those cases.

Code like this:

void f(const char *x) {
  if (!x)
    puts("null");
  else if ((uintptr_t)x == 1)
    puts("one");
  else if (x == (char*)2 || x == (char*)3)
    puts("two");
  else if ((intptr_t)x == 4)
    puts("four");
  else
    puts(x);
}

Now becomes a switch:

define void @f(i8* %x) nounwind ssp {
entry:
  %magicptr23 = ptrtoint i8* %x to i64            ; <i64> [#uses=1]
  switch i64 %magicptr23, label %if.else16 [
    i64 0, label %if.then
    i64 1, label %if.then2
    i64 2, label %if.then9
    i64 3, label %if.then9
    i64 4, label %if.then14
  ]

Note that LLVM's own DenseMap uses magic pointers.

44965f1107 fix logical-select to invoke filecheck right, and fix hte instcombine 
xform it is checking to actually pass.  There is no need to match
m_SelectCst<0, -1> since instcombine canonicalizes that into not(sext).

Add matches for sext(not(x)) in addition to not(sext(x)).

1604115c5a Move --march, --mcpu, and --mattr from JIT/TargetSelect.cpp to lli.cpp. 
llc.cpp also defined these flags, meaning that when I linked all of LLVM's
libraries into a single shared library, llc crashed on startup with duplicate
flag definitions.  This patch passes them through the EngineBuilder into
JIT::selectTarget().

94fe5501b7 When the scheduler unfold a load folding instruction it move some of the predecessors to the unfolded load. It decides what gets moved to the load by checking whether the new load is using the predecessor as an operand. The check neglects the cases whether the predecessor is a flagged scheduling unit.

9761f067f8 An empty global constant (one of size 0) may have a section immediately 
following it. However, the EmitGlobalConstant method wasn't emitting a body for
the constant. The assembler doesn't like that. Before, we were generating this:

  .zerofill __DATA, __common, __cmd, 1, 3

This fix puts us back to that semantic.

c7e8107ff2 Do not reassociate expressions with i1 type. SimplifyCFG converts some 
short-circuited conditions to AND/OR expressions, and those expressions
are often converted back to a short-circuited form in code gen.  The
original source order may have been optimized to take advantage of the
expected values, and if we reassociate them, we change the order and
subvert that optimization.  Radar 7497329.

a44be8b7f3 Disable external stubs for X86-32 and X86-64 
Instruction selection for X86 now can choose an instruction
sequence that will fit any address of any symbol, no matter
the pointer width. X86-64 uses a mov+call-via-reg sequence
for this.
