MSAA is only supported for 64KB_{R,Z}_X modes, so the micro tile
optimization that we use on gfx9 and earlier does not work.
Be very explicit about how the swizzle mode of the temporary surface is
selected.

For pipelines without API GS. We will later expand this to cover NGG
geometry shaders as well.
Note that the vtx offset passed into the GS part is just the
vertex index multiplied by VGT_ESGS_RING_ITEMSIZE.

Addrlib doesn't provide this info. Because DCC is linear, at least
on GFX8, it's easy to compute the size of one slice.

Currently libdrm_amdgpu provides a typedef of the various handles. While
the goal was to make those opaque, it effectively became part of the API
To the best of my knowledge there are two ways to have opaque handles:
- "typedef void *foo;" - rather messy IMHO
- "stuct foo;" and use "struct foo *" through the API
In our case amdgpu_device_handle is used only internally, plus
respective code is not used or applicable for r300 and r600. Hence we
copied the typedef.
Seemingly this will be a problem since libdrm_amdgpu wants to change the
API, while not updating the code(?).
Either way, we can safely s/amdgpU_device_handle/void */ and carry on.

The initial prototype used a processor-specific symbol type, but
feedback suggests that an approach using processor-specific section
name that encodes the alignment analogous to SHN_COMMON symbols is
preferred.
This patch keeps both variants around for now to reduce problems
with LLVM compatibility as we switch branches around.
This also cleans up the error reporting in this function.

inaccessiblememonly means that it doesn't modify memory accesible via
normal LLVM pointers. This lets LLVM's dead store elimination, memcpy
forwarding, etc. ignore functions with this attribute. We don't
represent descriptors as pointers, so this property is always true of
buffer and image stores. There are plans to represent descriptors via
pointers, but this just means that now nothing is inaccessiblememonly,
as LLVM will then understand loads/stores via its usual alias analysis.
Radeonsi was mistakenly only setting it if the driver could prove that
there were no reads, and then it was cargo-culted into ac_llvm_build
and ac_llvm_to_nir. Rip it out of everything.

Upcoming changes to LLVM will emit LDS objects as symbols in the ELF
symbol table, with relocations that will be resolved with this change.
Callers will also be able to define LDS symbols that are shared between
shader parts. This will be used by radeonsi for the ESGS ring in gfx9+
merged shaders.

Using an explicit linker instead of just concatenating .text
sections will allow us to start using .rodata sections and
explicit descriptions of data on LDS that is shared between
stages.
