Brian Favela e7e90dd1c1 [AMDGPU] Adding multiple use analysis to SIPeepholeSDWA (#94800) ...

Allow for multiple uses of an operand where each instruction can be
promoted to SDWA.

For instance:

; v_and_b32 v2, lit(0x0000ffff), v2
; v_and_b32 v3, 6, v2
; v_and_b32 v2, 1, v2

Can be folded to:
; v_and_b32 v3, 6, sel_lo(v2)
; v_and_b32 v2, 1, sel_lo(v2)
