Matt Arsenault 687ec75d10 DAG: Change behavior of fminnum/fmaxnum nodes
Introduce new versions that follow the IEEE semantics
to help with legalization that may need quieted inputs.

There are some regressions from inserting unnecessary
canonicalizes when these are matched from fast math
fcmp + select which should be fixed in a future commit.

Matt Arsenault 118c47b6d1 AMDGPU: Split amdgcn/r600 fminnum/fmaxnum tests
R600 breaks on too many things to usefully test changes
with ieee_mode on vs. off.

Matt Arsenault 8f9dde94b7 AMDGPU: Stop wasting argument registers with v3i32/v3f32
SelectionDAGBuilder widens v3i32/v3f32 arguments to
to v4i32/v4f32 which consume an additional register.
In addition to wasting argument space, this produces extra
instructions since now it appears the 4th vector component has
a meaningful value to most combines.

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).

Matt Arsenault 7aad8fd8f4 Enable FeatureFlatForGlobal on Volcanic Islands
This switches to the workaround that HSA defaults to
for the mesa path.

This should be applied to the 4.0 branch.

Matt Arsenault 9a19c240c0 AMDGPU: Materialize sign bits with bfrev
If a constant is the same as the reverse of an inline immediate,
this is 4 bytes smaller than having to embed a 32-bit literal.
