Most of this is ported over, except some omissions:
- array_filter, array_key_exists (suspected we had coverage already;
one is a bytecode, and one was rewritten in hhas recently)
- some random cases distinguishing init_null_variant vs. null_variant
A poor man's formatter since I didn't like any of the other ones I found. The original C++ source sometimes put newlines and sometimes not.
Codemods:
codemod '([;{}])([^\n])' '\1\n\2'
codemod -m '\s*<\?php\s+' '<?php\n\n'
codemod '\t' ' '
I hand-fixed all the failing tests
