This adds new `Int8`, `Int16`, `Int32` and `Int64` data types to the compiler, thus working towards properly specified integer types as discussed in #1048. In addition, the following changes / corrections are made: * Support casts from `Char`, `String`, and `Double` to all integer types (and back). This fixes #1270. * Make sure that all casts to limited-precision integers are properly bounds checked (this was not the case so far for casts from `String` and `Double` to `Int`) * Add a thorough set of tests to make sure all bounds checks work correctly for all supported casts and arithmetic operations
