Jessica Paquette 0d774aa131 Add REQUIRES line to machine-size-remarks
Just was made aware that this is necessary for tests outside of
the X86 subdirectory. Add a REQUIRES line to make sure bots that
don't enable x86 are happy.

; Make sure that machine-level size remarks work.
; Test the following:
; - When we create a MachineFunction (e.g, during instruction selection), it
; has a size of 0.
; - The initial size of the function after filling it is positive.
; - After that, we can increase or decrease the size of the function.
; - ... The final size must be positive.
; - ... The delta can be negative or positive.
