Add script for diffing two fish profile runs Came in handy for tracking down the performance regression in #5219. This will take the output of two (necessarily identical) `fish --profile ...` runs and produce a third profile log in which all times are the difference between the first and the second profile provided. (I'm not sure if build_tools is the right place for it, but I think it's OK?)

# Compares the output of two fish profile runs and emits the time difference between

# Usage: ./diff_profiles.fish profile1.log profile2.log > profile_diff.log

Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent.
