Detailed Description

Insn candidates for rematerialization.  The candidate insn should
have the following properies:
o no any memory (as access to memory is non-profitable)
o no INOUT regs (it means no non-paradoxical subreg of output reg)
o one output spilled pseudo (or reload pseudo of a spilled pseudo)
o all other pseudos are with assigned hard regs.
