af53a87052 Go through all kinds of trouble to mark 'blr' as having a predicate operand 
that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

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)

059ca0f5b7 fix some assumptions that pointers can only be 32-bits. With this, we can 
now compile:

void test1() {
  X = 0;
}

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

4a45abf66e Fix a problem exposed by the local allocator. CALL instructions are not marked 
as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.

9a2a497284 Switch PPC over to a call-selection model where the lowering code creates 
the copyto/fromregs instead of making the PPCISD::CALL selection code create
them.  This vastly simplifies the selection code, and moves the ABI handling
parts into one place.

37efe67645 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

90564f26d1 Implement an important entry from README_ALTIVEC: 
If an altivec predicate compare is used immediately by a branch, don't
use a (serializing) MFCR instruction to read the CR6 register, which requires
a compare to get it back to CR's.  Instead, just branch on CR6 directly. :)

For example, for:
void foo2(vector float *A, vector float *B) {
  if (!vec_any_eq(*A, *B))
    *B = (vector float){0,0,0,0};
}

We now generate:

_foo2:
        mfspr r2, 256
        oris r5, r2, 12288
        mtspr 256, r5
        lvx v2, 0, r4
        lvx v3, 0, r3
        vcmpeqfp. v2, v3, v2
        bne cr6, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
        vxor v2, v2, v2
        stvx v2, 0, r4
        mtspr 256, r2
        blr
LBB1_2: ; UnifiedReturnBlock
        mtspr 256, r2
        blr

instead of:

_foo2:
        mfspr r2, 256
        oris r5, r2, 12288
        mtspr 256, r5
        lvx v2, 0, r4
        lvx v3, 0, r3
        vcmpeqfp. v2, v3, v2
        mfcr r3, 2
        rlwinm r3, r3, 27, 31, 31
        cmpwi cr0, r3, 0
        beq cr0, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
        vxor v2, v2, v2
        stvx v2, 0, r4
        mtspr 256, r2
        blr
LBB1_2: ; UnifiedReturnBlock
        mtspr 256, r2
        blr

This implements CodeGen/PowerPC/vec_br_cmp.ll.
