Chris Lattner 9834ad2fc6 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.

Chris Lattner 7e742e46ac 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

Chris Lattner 2d4e8f7e86 Add some patterns for globals, so we can now compile this: 
static unsigned long long X, Y;
void test1() {
  X = Y;
}

into:

_test1:
        lis r2, ha16(_Y)
        lis r3, ha16(_X)
        ld r2, lo16(_Y)(r2)
        std r2, lo16(_X)(r3)
        blr

Chris Lattner 638ee4ee15 Upgrade some load/store instructions to use the proper addressing mode stuff.

Chris Lattner a5190ae7a9 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 :)
