a9158af0 - [AMDGPU][SIInsertWaitcnt][NFC] Replace LastFlat array with distinct variables (#185993)

[AMDGPU][SIInsertWaitcnt][NFC] Replace LastFlat array with distinct variables (#185993) We only seem to be using LastFlat[LOAD_CNT] and LastFlat[DS_CNT] so it doesn't look like there is a good reason for using an array. Also, we seem to be operating on all elements of the array while merging, which is not great.
