Rename the pass name and give it descriptive documentation.

Update a couple tests to account for RenumberBlocks not having run yet.


dhoekwater added a comment.

Remove FIXMEs. We probably will want to rename preEmitPass functions to something
more reflective of the functions' purposes.


Because branch relaxation needs to factor in if branches target
a block in the same section or a different one, it needs to run
after the Basic Block Sections / Machine Function Splitting passes.

Because Jump table compression relies on block offsets remaining
fixed after the table is compressed, we must also move the JT
compression pass.
