x86/asm: Use %c/%n instead of %P operand modifier in asm templates
The "P" asm operand modifier is a x86 target-specific modifier.
When used with a constant, the "P" modifier emits "cst" instead of
"$cst". This property is currently used to emit the bare constant
without all syntax-specific prefixes.
The generic "c" resp. "n" operand modifier should be used instead.
No functional changes intended.
