parse.y (struct parser_params): pack to 4 cache lines on x86-64
This reduces the struct from 256 (from 288) bytes on my x86-64
system, allowing the struct to fit cleanly into 4 cache lines
(if a malloc implementation allows it).
* parse.y (struct parser_params): pack: 88 => 256 bytes on 64-bit
[ruby-core:70034] [Feature #11371]
