2f616bff7e This is a general clean up of the PowerPC ABI. Address several problems and
bugs including making sure that the TOS links back to the previous frame,
that the maximum call frame size is not included twice when using frame
pointers, no longer growing the frame on calls, double storing of SP and
a cleaner/faster dynamic alloca.

1b0a2d8370 fix a regression that I introduced. stdu should scale the offset by 4
before printing it.

8e28b5c426 Stop using isTwoAddress, switching to operand constraints instead.
Tell the codegen emitter that specific operands are not to be encoded, fixing
JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate
even when general preinc loads are not enabled).

6a5339ba65 Rework PPC64 calls. Now we have a LR8/CTR8 register which the PPC64 calls
clobber.  This allows LR8 to be save/restored correctly as a 64-bit quantity,
instead of handling it as a 32-bit quantity.  This unbreaks ppc64 codegen when
the code is actually located above the 4G boundary.

3ae5eef027 Add some more immediate patterns. This allows us to compile:
void test6() {
  Y = 0xABCD0123BCDE4567;
}

into:

_test6:
        lis r2, -21555
        lis r3, ha16(_Y)
        ori r2, r2, 291
        rldicr r2, r2, 32, 31
        oris r2, r2, 48350
        ori r2, r2, 17767
        std r2, lo16(_Y)(r3)

eded521a17 Instead of li/xoris use li/oris. Note that this doesn't work if bit 15 is
set, so disable the pattern in that case.

0ea70b219a 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
        ori r0,r0,3840
        std r0,lo16(_Y)(r2)
        blr

f27bb6de10 Add some patterns for globals, so we can now compile this:

        lis r3, ha16(_X)

059ca0f5b7 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
