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. llvm-svn: 341885

; 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.
