f93ea63eaa Enable EH on PPC Darwin. This basically works; there
are a couple of issues that show up with the optimizer,
but I don't think they're really EH problems.
(llvm-gcc testsuite users note:  By default the testsuite
uses the unwinding code that's built as part of your local
llvm-gcc, which does not work.  You need to trick it into
using the installed system unwinding code to get useful
results.)

e5af8b6e5c Add "mayHaveSideEffects" and "neverHasSideEffects" flags to some instructions. I
based what flag to set on whether it was already marked as
"isRematerializable". If there was a further check to determine if it's "really"
rematerializable, then I marked it as "mayHaveSideEffects" and created a check
in the X86 back-end similar to the remat one.

a608afb52e Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

c6fd78dec1 Fix the JIT encoding of cmp*ss, which aborts with this assertion currently:
X86CodeEmitter.cpp:378: failed assertion `0 && "Immediate size not set!"'

I *think* this is right, but Evan, please verify.  It also looks like
CMPSDrr and maybe others are missing this info.  Evan, plz investigate.

SelectionDAG::getConstant, in the same way as vector floating-point
constants. This allows the legalize expansion code for @llvm.ctpop and

f6c2838f36 - Improved v8i16 shuffle lowering. It now uses pshuflw and pshufhw as much as
possible before resorting to pextrw and pinsrw.
- Better codegen for v4i32 shuffles masquerading as v8i16 or v16i8 shuffles.
- Improves (i16 extract_vector_element 0) codegen by recognizing
  (i32 extract_vector_element 0) does not require a pextrw.

f7c53191c0 Move TargetData::hostIsLittleEndian out of line, which means we
don't have to #include config.h in it.  #including config.h breaks
other projects that have their own autoconf stuff and try to #include
the llvm headers.  One obscure example is llvm-gcc.

b511799808 Disable cfi directives for now, darwin does't support them.
These should probably be something like:

  CFI(".cfi_def_cfa_offset 16\n")

where CFI is defined to a noop on darwin and other platforms
that don't support those directives.
