Don Isaac 27030b9eb4 perf(lexer): use bitshifting when parsing known integers (#3296) ... ## What This PR Does - perf(lexer): use bit shifting when parsing hex, octal, and binary integers instead of `mul_add`-ing on `f64`s. Check out the difference in assembly generated [here](https://godbolt.org/z/zMEKaeYzh) - perf(lexer): skip redundant utf8 check when parsing BigInts - refactor(lexer): remove `unsafe` usage (as per @overlookmotel's request [here](https://github.com/oxc-project/oxc/pull/3283#issuecomment-2111814598)) - test(lexer): add numeric parsing unit tests I don't expect this PR to have a large performance improvement, since the most common case (`Kind::Decimal`) is not affected. We could do this, however, by splitting `Kind::Decimal` into `Kind::DecimalFloat` and `Kind::DecimalInt` when the lexer encounters a `.`		2024-05-17 09:39:10 +08:00
