[InlineSpiller] Relax re-materialization restriction for statepoint
We should be careful to allow count of re-materialization of operands to be less
then number of physical registers.
STATEPOINT instruction has a variable number of operands and potentially very big.
So re-materialization for all operands is disabled at the moment if restrict-statepoint-remat is true.
The patch relaxes the re-materialization restriction for STATEPOINT instruction allowing it for
fixed operands. Specifically it is about call target.
