[JSC] Sort opcodes to remove padding from metadata table
https://bugs.webkit.org/show_bug.cgi?id=252055
rdar://105276503
Reviewed by Yusuke Suzuki.
Sort the opcodes by metadata alignment requirements. We start with 8-byte
aligned,
followed by 4-byte, etc. The memory savings are minimal (too small to measure
with
confidence), but they are also free.
