In preparation for a patch, add a test for MachineCombiner in RISC-V
CodeGen, where the MachineBasicBlock has 33 live registers (just above
the general-purpose register limit of 32 on RISC-V). Since
MachineCombiner kicks in, it leads to increased register pressure,
resulting in spills. The next patch will turn off MachineCombiner for
this case.
