Alexander Timofeev c4d256a590 [AMDGPU] Come back patch for the 'Assign register class for cross block values according to the divergence.'
Detailed description:

    After https://reviews.llvm.org/D59990 submit several issues were discovered.
    Changes in common code were preserved but AMDGPU specific part was reverted to keep the backend working correctly.

    Discovered issues were addressed in the following commits:

    https://reviews.llvm.org/D67662
    https://reviews.llvm.org/D67101
    https://reviews.llvm.org/D63953
    https://reviews.llvm.org/D63731

    This change brings back AMDGPU specific changes.

Matt Arsenault 51a05d72ae AMDGPU: Drop remnants of byval support for shaders
Before 2018, mesa used to use byval interchangably with inreg, which
didn't really make sense. Fix tests still using it to avoid breaking
in a future commit.

Nicolai Haehnle 1045928aab AMDGPU: Convert test cases to the dimension-aware intrinsics
Summary:
Also explicitly port over some tests in llvm.amdgcn.image.* that were
missing. Some tests are removed because they no longer apply (i.e.
explicitly testing building an address vector via insertelement).

This is in preparation for the eventual removal of the old-style
intrinsics.

Some additional notes:
- constant-address-space-32bit.ll: change some GCN-NEXT to GCN because
  the instruction schedule was subtly altered
- insert_vector_elt.ll: the old test didn't actually test anything,
  because %tmp1 was not used; remove the load, because it doesn't work
  (Because of the amdgpu_ps calling convention? In any case, it's
  orthogonal to what the test claims to be testing.)

Matt Arsenault 3dbeefa978 AMDGPU: Mark all unspecified CC functions in tests as amdgpu_kernel
Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.

Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).

Sanjoy Das 3336f681e3 [Verifier] Add verification for TBAA metadata
Summary:
This change adds some verification in the IR verifier around struct path
TBAA metadata.

Other than some basic sanity checks (e.g. we get constant integers where
we expect constant integers), this checks:

 - That by the time an struct access tuple `(base-type, offset)` is
   "reduced" to a scalar base type, the offset is `0`.  For instance, in
   C++ you can't start from, say `("struct-a", 16)`, and end up with
   `("int", 4)` -- by the time the base type is `"int"`, the offset
   better be zero.  In particular, a variant of this invariant is needed
   for `llvm::getMostGenericTBAA` to be correct.

 - That there are no cycles in a struct path.

 - That struct type nodes have their offsets listed in an ascending
   order.

 - That when generating the struct access path, you eventually reach the
   access type listed in the tbaa tag node.

Matt Arsenault ad55ee5869 AMDGPU: Don't required structured CFG
The structured CFG is just an aid to inserting exec
mask modification instructions, once that is done
we don't really need it anymore. We also
do not analyze blocks with terminators that
modify exec, so this should only be impacting
true branches.

Add parsing and printing of image operands. Matches legacy sp3 assembler.
Change image instruction order to have data/image/sampler operands in the beginning. This is needed because optional operands in MC are always last.

Tom Stellard 1397d49ef5 AMDGPU/SI: Make sure MIMG descriptors and samplers stay in SGPRs
Summary:
It's possible to have resource descriptors and samplers stored in
VGPRs, either by a VMEM instruction or in the case of samplers,
floating-point calculations.  When this happens, we need to use
v_readfirstlane to copy these values back to sgprs.

Matt Arsenault 018179fc46 AMDGPU: Remove old sample intrinsics
I did my best to try to update all the uses in tests that
just happened to use the old ones to the newer intrinsics.

I'm not sure I got all of the immediate operand conversions
correct, since the value seems to have been ignored by the
old pattern but I don't think it really matters.

This is not yet complete, but gets most of the important ones.
llvm.AMDGPU.* intrinsics used by mesa and libclc are still handled
for compatability for now.
