Sameer Sahasrabuddhe a34a024812 [AMDGPU][SIInsertWaitCnts] skip meta instructions early (#145720) ...

When iterating over a block, meta instructions have no effect on wait counts,
but their presence drops the reference to earlier waitcnt instructions before
they are processed. This results in spurious wait counts, which do not affect
correctness, but are also not required in the resulting program. Skipping meta
instructions as soon as they are seen cleans this up.
