Add some more immediate patterns.  This allows us to compile:

void test6() {

        lis r2, -21555

Instead of li/xoris use li/oris.  Note that this doesn't work if bit 15 is

Add some 64-bit logical ops.
Split imm16Shifted into a sext/zext form for 64-bit support.
Add some patterns for immediate formation.  For example, we now compile this:

static unsigned long long Y;
void test3() {
  Y = 0xF0F00F00;
}

into:

_test3:
        li r2, 3840
        lis r3, ha16(_Y)
        xoris r2, r2, 61680
        std r2, lo16(_Y)(r3)
        blr

GCC produces:

_test3:
        li r0,0
        lis r2,ha16(_Y)
        ori r0,r0,61680
        sldi r0,r0,16

Remove some now-unneeded casts from instruction patterns.  With the casts

Don't require src/dst patterns to be able to fully resolve their types,
because information about one can help refine the other.  This allows us to
write:

def : Pat<(i32 (extload xaddr:$src, i8)),
          (LBZX xaddr:$src)>;

as:

def : Pat<(extload xaddr:$src, i8),
          (LBZX xaddr:$src)>;

because tblgen knows LBZX returns i32.

Make sure to use the result of the pattern to infer the result type of the
instruction, and the result type of the instruction to refine the pattern.
This allows us to write things like this:

def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (v2i64 VR128:$src)>;

as:
def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (VR128:$src)>

Do not hardcode random paths into the makefile.  Make the user specify the
SDK to use when building "universal" on Mac OS/X, if they want to use a
specific one.

Upgrade some load/store instructions to use the proper addressing mode stuff.

In 64-bit mode, addr mode operands use G8RC instead of GPRC.

fix some assumptions that pointers can only be 32-bits.  With this, we can
now compile:

static unsigned long X;
void test1() {
  X = 0;
}

into:

_test1:
        lis r2, ha16(_X)
        li r3, 0
        stw r3, lo16(_X)(r2)
        blr

Totally amazing :)

Don't pass target name into TargetData anymore, it is never used or needed.

Don't pass target name into TargetData anymore, it is never used or needed.
Remove explicit casts to std::string now that there is no overload resolution
issues in the TargetData ctors.

Simplify the targetdata ctor by not passing in a "targetname" which is always
ignored.

Remove ctor with each piece specifyable (which causes overload ambiguities),
add a new init method.

Only count instructions as code size, not constant pools and other per-function stuff.

Document the subtarget features better, make sure that 64-bit mode, 64-bit
support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

Rename some subtarget features.  A CPU now can *have* 64-bit instructions,
can in 32-bit mode we can choose to optionally *use* 64-bit registers.
