```
stage1: eliminate the IrInst base struct

This commit intentions to have no functional changes. The only purpose
is to delete the struct IrInst, which is the common base struct that
both IrInstSrc (ZIR) and IrInstGen (AIR) instructions embed.

This untangles stage1 ZIR and AIR memory layout, paving the way for a
following commit to reduce memory usage.
