Shugo Maeda 0728ece031 [ruby/prism] Avoid a quadratic walk when parsing long call chains ...

parse_expression_terminator runs after every infix operator and called
pm_block_call_p, which walks the whole receiver chain, even when the
binding power alone already decided the result. Check the binding power
first; pm_block_call_p is pure, so the condition is unchanged.

Parsing "a" followed by 8000 ".b" links drops from 44.8ms to 0.46ms.
