The compiler should work in code units of the TARGET string encoding when building tries for string switches. Using its own string encoding would be incorrect if it differs from the target encoding. Currently that would only occur if the compiler is built in a java/csharp grade (uses UTF-16 internally) and invoked to target high-level C (uses UTF-8). Another motivation for this change is to remove a place where the compiler behaviour depends on the setting of `--cross-compiling'. As of now, the `--cross-compiling' option has no effect. compiler/backend_libs.m: compiler/string_encoding.m: Add new module with helper predicates. compiler/ml_string_switch.m: Convert strings to/from code units in the target string encoding. compiler/ml_switch_gen.m: Remove restriction on compiling string switches using tries when `--cross-compiling' is enabled. compiler/notes/compiler_design.html: Document the new module.
