Juergen Ributzka 5cb9925acd [X86] Don't mark movabsq as cheap-as-move - it isn't that cheap.
A simple register copy on X86 is just 3 bytes, whereas movabsq is a 10 byte
instruction. Marking movabsq as not beeing cheap will allow LICM to move it
out of the loop and it also prevents unnecessary rematerializations if the
value is needed in more than one register.
