Revert "[CodeGenPrepare] Scan past debug intrinsics to find select candidates (NFC)"

Browse Source 
This causes crashes due to the interleaved dbg.value intrinsics being
left at the end of basic blocks, causing the actual terminators (br,
etc) to be not where they should be (not at the end of the block),
leading to later crashes.

Further discussion on the original commit thread.

This reverts commit r340368.
