R600/SI: fix shadow mapping for 1D and 2D array textures

It was conflicting with def TEX_SHADOW_ARRAY, which also handles them.

R600/SI: add sample and image intrinsics exposing all instruction fields

We need the intrinsics with offsets, so why not just add them all.
The R128 parameter will also be useful for reducing SGPR usage.
GL_ARB_image_load_store also adds some image GLSL modifiers like "coherent",
so Mesa will probably translate those to slc, glc, etc.

When LLVM 3.5 is released, I'll switch Mesa to these new intrinsics.

R600/SI: Use i32 vectors for resources and samplers

This affects new intrinsics only.

What surprises me is that v32i8 still works.

[PowerPC] Fix invalid displacement created by LocalStackAlloc

This commit fixes a bug in PPCRegisterInfo::isFrameOffsetLegal that
could result in the LocalStackAlloc pass creating an MI instruction
out-of-range displacement:
        %vreg17<def> = LD 33184, %vreg31; mem:LD8[%g](align=32)
        %G8RC:%vreg17 G8RC_and_G8RC_NOX0:%vreg31
(In final assembler output the top bits are stripped off, resulting
in a negative offset loading from below the stack pointer.)

Common code expects the isFrameOffsetLegal routine to verify whether
adding a given offset to the offset already present in the instruction
results in a valid displacement.  However, on PowerPC the routine
did not take the already present instruction offset into account.

This commit fixes isFrameOffsetLegal to add the instruction offset,
and updates a local caller (needsFrameBaseReg) to no longer add the
instruction offset itself before calling isFrameOffsetLegal.

[MC] Constify MCELF::GetVisibility and MCELF::getOther

These two routines didn't take a "const MCSymbolData &SD"
like the other MCELF::Get routines for some reason ...
