PPC/S390: [liftoff] Introduce emit_{i64,i32}_add with immediate

Browse Source 
Porting: 138d2dfcb1

Original comment:
   This allows immediates to be encoded directly into instructions, rather than
   mov-ing constants to registers first.

   This patch only changes emit_{i64,i32}_add, other emit_ functions will be changed once
   this approach has been approved.
