[AMDGPU] Remove implicit definition of register group when restoring the last sub-register after a spill
Extension of https://reviews.llvm.org/D141101 to remove the define flag from the last stack memory access. Fixes case where COPY instructions are used for some of the stack restoration, but the copies get optimized away during the machine-cp pass. Prior to this change, was possible to produce the following code: $agpr16_agpr17_agpr18_agpr19 = SCRATCH_LOAD_DWORDX4_ST 64, 0, implicit $exec, implicit $flat_scr, implicit-def $agpr16_agpr17_agpr18_agpr19_agpr20_agpr21_agpr22_agpr23_agpr24_agpr25_agpr26_agpr27_agpr28_agpr29_agpr30_agpr31 :: (load (s128) from %stack.17, align 4, addrspace 5) $agpr20_agpr21_agpr22_agpr23 = SCRATCH_LOAD_DWORDX4_ST 80, 0, implicit $exec, implicit $flat_scr :: (load (s128) from %stack.17 + 16, align 4, addrspace 5) $agpr24_agpr25_agpr26_agpr27 = SCRATCH_LOAD_DWORDX4_ST 96, 0, implicit $exec, implicit $flat_scr :: (load (s128) from %stack.17 + 32, align 4, addrspace 5) $agpr31 = COPY $agpr112, implicit $agpr16_agpr17_agpr18_agpr19_agpr20_agpr21_agpr22_agpr23_agpr24_agpr25_agpr26_agpr27_agpr28_agpr29_agpr30_agpr31 $agpr30 = COPY $agpr208, implicit $agpr16_agpr17_agpr18_agpr19_agpr20_agpr21_agpr22_agpr23_agpr24_agpr25_agpr26_agpr27_agpr28_agpr29_agpr30_agpr31 $agpr28_agpr29 = SCRATCH_LOAD_DWORDX2_ST 112, 0, implicit $exec, implicit $flat_scr, implicit-def $agpr16_agpr17_agpr18_agpr19_agpr20_agpr21_agpr22_agpr23_agpr24_agpr25_agpr26_agpr27_agpr28_agpr29_agpr30_agpr31 :: (load (s64) from %stack.17 + 48, align 4, addrspace 5) where `$agpr30 = COPY $agpr208` would be optimized away by `machine-cp` pass. Instead, change to: $agpr28_agpr29 = SCRATCH_LOAD_DWORDX2_ST 112, 0, implicit $exec, implicit $flat_scr :: (load (s64) from %stack.17 + 48, align 4, addrspace 5) Fixes #131386.
