[AMDGPU] Promote constant offset to the immediate by finding a new base with 13bit constant offset from the nearby instructions.
Summary: Promote constant offset to immediate by recomputing the relative 13bit offset from nearby instructions.
E.g.
s_movk_i32 s0, 0x1800
v_add_co_u32_e32 v0, vcc, s0, v2
v_addc_co_u32_e32 v1, vcc, 0, v6, vcc
s_movk_i32 s0, 0x1000
v_add_co_u32_e32 v5, vcc, s0, v2
v_addc_co_u32_e32 v6, vcc, 0, v6, vcc
global_load_dwordx2 v[5:6], v[5:6], off
global_load_dwordx2 v[0:1], v[0:1], off
=>
s_movk_i32 s0, 0x1000
v_add_co_u32_e32 v5, vcc, s0, v2
v_addc_co_u32_e32 v6, vcc, 0, v6, vcc
global_load_dwordx2 v[5:6], v[5:6], off
global_load_dwordx2 v[0:1], v[5:6], off offset:2048
