    Make renamer to be more flexible with parens in the LHS of the rules · 4d3acbcf
    Zejun Wu authored and Marge Bot's avatar Marge Bot committed 
    We used to reject LHS like `(f a) b` in RULES and requires it to be written as
`f a b`. It will be handy to allow both as the expression may be more
readable with extra parens in some cases when infix operator is involved.
Espceially when TemplateHaskell is used, extra parens may be added out of
user's control and result in "valid" rules being rejected and there
are not always ways to workaround it.

Fixes #24621
