ab05ab59a7 [CostModel][AMDGPU] Fix instructions costs estimation for vector types.
1. Fixed vector instructions costs estimations incosistency - removed different
   logic for "not simple types" since it biases costs for these types.
2. Fixed legalization penalty for vectors too big for the target: changed from
   overwrite default legalization cost value estimation to added penalty.
3. Fixed few typos in tests.

9068c20965 [AMDGPU][CostModel] Refine cost model for half- and quarter-rate instructions.
1. Throughput and codesize costs estimations was separated and updated.
2. Updated fdiv cost estimation for different cases.
3. Added scalarization processing for types that are treated as !isSimple() to
improve codesize estimation in getArithmeticInstrCost() and
getArithmeticInstrCost(). The code was borrowed from TCK_RecipThroughput path
of base implementation.

Next step is unify scalarization part in base class that is currently works for
TCK_RecipThroughput path only.

e0c1f9e76d AMDGPU: Partially fix default device for HSA
There are a few different issues, mostly stemming from using
generation based checks for anything instead of subtarget
features. Stop adding flat-address-space as a feature for HSA, as it
should only be a device property. This was incorrectly allowing flat
instructions to select for SI.

Increase the default generation for HSA to avoid the encoding error
when emitting objects. This has some other side effects from various
checks which probably should be separate subtarget features (in the
cost model and for dealing with the DS offset folding issue).

Partial fix for bug 41070. It should probably be an error to try using
amdhsa without flat support.

e30aa6a136 [AMDGPU] Prepare for introduction of v3 and v5 MVTs
AMDGPU would like to have MVTs for v3i32, v3f32, v5i32, v5f32. This
commit does not add them, but makes preparatory changes:

* Fixed assumptions of power-of-2 vector type in kernel arg handling,
  and added v5 kernel arg tests and v3/v5 shader arg tests.

* Added v5 tests for cost analysis.

* Added vec3/vec5 arg test cases.

Some of this patch is from Matt Arsenault, also of AMD.

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).
