Detailed Description

The AMDGPUAsmPrinter is used to print both assembly string and also binary code.

When passed an MCAsmStreamer it prints assembly and when passed an MCObjectStreamer it outputs binary code.

createOccupancy()

const AMDGPUMCExpr * createOccupancy	(	unsigned	InitOcc,
		const MCExpr *	NumSGPRs,
		const MCExpr *	NumVGPRs,
		unsigned	DynamicVGPRBlockSize,
		const GCNSubtarget &	STM,
		MCContext &	Ctx )

Mimics GCNSubtarget::computeOccupancy for MCExpr.

Remove dependency on GCNSubtarget and depend only only the necessary values for said occupancy computation. Should match computeOccupancy implementation without passing STM on.
