Matt Arsenault 5aa6e246a1 AMDGPU/GlobalISel: Legalize f64 G_FFLOOR for SI
Use cmp ord instead of cmp_class compared to the DAG version for the
nan check, but mostly try to match the existsing pattern.

I think the sign doesn't matter for fract, so we could do a little
better with the source modifier matching.

I think this is also still broken as in D22898, but I'm leaving it
as-is for now while I don't have an SI system to test on.

Matt Arsenault ea956685a1 GlobalISel: Implement s32->s64 G_FPTOSI lowering
Port directly from DAG version.

The lowering for G_FPTOUI used to fail on AMDGPU because it uses
G_FPTOSI.

Daniel Sanders acc008cb0c [globalisel] Remove redundant -global-isel option from tests that use -run-pass. NFC
As Roman Tereshin pointed out in https://reviews.llvm.org/D45541, the
-global-isel option is redundant when -run-pass is given. -global-isel sets up
the GlobalISel passes in the pass manager but -run-pass skips that entirely and
configures it's own pipeline.
