The bounds of a `switch` range case were checked against the tag but never converted to its type, unlike a single case value, so untyped bounds took their own default type. Against a `cstring` tag `"0"..="9"` became `string` bounds, and converting a constant `string` to `cstring` in the backend crashed the compiler. A `cstring16` or `string16` tag failed with an invalid conversion from `string` instead. Convert the bounds to the tag's type, which also gives an invalid bound the same error as a single case value. A constant `cstring` or `cstring16` tag forced the `string` comparison procedures rather than its own, so it failed with a missing `cstring_le` or `cstring16_le` even with typed bounds. `lb_get_const_string` expected the data pointer of a constant string to be a zero index GEP, which LLVM folds to the global itself, and it is null for an empty string, so it read an invalid constant expression. Handle both, and have a converted empty string point to its terminator like a constant `cstring` rather than be nil. Fixes #7853

The Odin Programming Language
Odin is a general-purpose programming language with distinct typing, built for high performance, modern systems, and built-in data-oriented data types. The Odin Programming Language, the C alternative for the joy of programming.
