Very minor clean-up
Moved `LanguageCompiler.getSrcDir()` to `FileUtil` as `selectPath()`
Added symbols for `Byte` and its supporting wrapper classes / getter interfaces (#1738)
Added support for boxing and unboxing between `Byte`and `byte` and treating it as a separate type instead of a special type of `Integer` (#1738)
Added support for `Byte` type to `checkForBitwiseOperators()` (#1738)
Added `getByteArray()` support function (#1738)
Added support for `Byte` type to `makeIndexedAccess()` and `makeDefaultExprForType()` (#1738)
Added support for treating `byte` as the new `Byte` type instead of a special kind of `Integer` (#1738)
Fixed most of the tests that failed because of the addition of the new `Byte` type (#1738)
Don't special case conversions to `byte` anymore now that we have a proper `Byte` type (#1738)
