Log Message:
amdgpu: Mark float-dependent variables volatile.

This way they are computed -- using FP instructions -- before
DC_FP_END, after which point FP instructions will trap or behave
unpredictably.

This is a workaround, not a proper solution -- really, the
DC_FP_START/END calls should happen in a separate compilation unit
built without -mhard-float or whatever, but that's a lot more work to
make happen for now.
