9c61dcf1aa Codegen things like:
<int -1, int -1, int -1, int -1>
and
 <int 65537, int 65537, int 65537, int 65537>

Using things like:
  vspltisb v0, -1
and:
  vspltish v0, 1

instead of using constant pool loads.

This implements CodeGen/PowerPC/vec_splat.ll:splat_imm_i{32|16}.

e5ba580ab0 Add support for "ri" addressing modes where the immediate is a 14-bit field
which is shifted left two bits before use.  Instructions like STD use this
addressing mode.

13feb58aa1 Print absolute memory references like this:
lwz r2, 8(0)
instead of this:
       lwz r2, 8(r0)

This fixes the llc/llc-beta failures on PPC last night.

e3f01570c1 Implement the PPC inline asm "L" modifier. This allows us to compile:
long long test(long long X) {
  __asm__("foo %0 %L0 %1 %L1" : "=r"(X): "r"(X));
  return X;
}

to:
        foo r2 r3 r2 r3

4c1aa86657 - Added option -relocation-model to set relocation model. Valid values include static, pic,
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.

0d7db6f79a If we have zero initialized data with external linkage, use .zerofill to
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.

88276b887c Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register.  This also requires some asm printer work
to satisfy the darwin assembler.

For
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = add <4 x float> %tmp1, %tmp1
  store <4 x float> %tmp2, <4 x float> *%a
  ret void
}

We now produce:
_foo:
        lvx v0, 0, r3
        vaddfp v0, v0, v0
        stvx v0, 0, r3
        blr

Instead of:
_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr
