The operand flag word used in ISD::INLINEASM is an i32 not a pointer. NFC.

Summary:
This is part of the work to support memory constraints that behave
differently to 'm'. The subsequent patches will expand on the existing
encoding (which is a 32-bit int) and as a result in some flag words will no
longer fit into an i16. This problem only affected the MSP430 target which
appears to have 16-bit pointers.
