Manman Ren c7e0a8178a Register allocator: set CSRFirstUseCost to 5 for ARM64. ...

A value of 5 means if we have a split or spill option that has a really
low cost (1 << 14 is the entry frequency), we will choose to spill
or split the really cold path before using a callee-saved register.

This gives us the performance benefit on SPECInt2k and is also conservative.
