Replace spills to memory with spills to registers, if possible. This applies mostly to predicate registers (both scalar and vector), since they are very limited in number. A spill of a predicate register may happen even if there is a general-purpose register available. In cases like this the stack spill/reload may be eliminated completely. This optimization will consider all stack objects, regardless of where they came from and try to match the live range of the stack slot with a dead range of a register from an appropriate register class. llvm-svn: 260758
