2b7a271c71 dag combine sext(setcc) -> vsetcc before legalize. To make this safe, 
VSETCC must define all bits, which is different than it was documented
to before.  Since all targets that implement VSETCC already have this
behavior, and we don't optimize based on this, just change the 
documentation.  We now get nice code for vec_compare.ll

66c6324fcf DWARF requires frame moves be specified at specific times. If you have a 
prologue like this:

__Z3fooi:
Leh_func_begin1:
LBB1_0: ## entry
        pushl   %ebp
Llabel1:
        movl    %esp, %ebp
Llabel2:
        pushl   %esi
Llabel3:
        subl    $20, %esp
        call    "L1$pb"
"L1$pb":
        popl    %esi

The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp,
%ebp" makes %ebp the new stack frame register, so that needs to be specified in
DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs
to be specified in DWARF.

Before, all of this logic was in one method. This didn't work too well, because
as you can see there are multiple FDE line entries that need to be created.

This fix creates the "MachineMove" objects directly when they're needed; instead
of waiting until the end, and losing information.

post-increment with pre-increment."

a9b7d60d67 Eliminate the static constructors and locks from DynamicLibrary.cpp. 
This fixes PR4512 and eliminating static ctors is always good.  Losing
thread safety is unfortunate, but the code is just incredibly poorly
designed.

If someone is interested, the "right" solution is to split
DynamicLibrary.cpp into two separate pieces: a stateless piece in
libsystem, and a simple support file in libsupport that has the
"state" (e.g.  AddSymbol) in managed static objects.

Doing this would both fix memory leaks we already have, as well as make
the code thread safe again.  it would also make sense to move all the
unix specific code in System/DynamicLibrary.cpp into 
System/Unix/DynamicLibrary.inc.
