Move push literal number opcodes to basic opcodes (#4609)

Browse Source 
`obj[number]` is a widely used structure especially for array element indexing, however super property assignment is not.
This patch moves super-assignment opcodes to ext opcodes and fills the freed 3 basic opcodes with push-literal-number ones.
