regalloc+emit: get rid of xsave/xrestore hack
Was used for situation where we needed to spill more than 1 temporary
and have to use a register that is already used. Instead of push/pop, we
can just allocate and set aside specific stack slots for this purpose.
Also, reworked linearscan() interval sets to separate FPR/GPR intervals.
