94e3f8895b Update xcode project for xcode 10.0. 
Xcode 10.0 no longer supports building for IA-32, so the MPS can no longer support building for xci3ll using Xcode.
Revise example Scheme interpreter so that it can be compiled even if getopt.h includes unistd.h (as it does on macOS).

8c5bb6ae3c Turn on -wunreachable-code for gcc and clang. 
Remove unreachable code:
* No need to have different debug options or structured allocation classes for different platforms.
* Don't use STATISTIC_BEGIN, use STATISTIC_STAT.
* #ifdef away the unused code in zmess.c for testing ControlAlloc failure.
* Remove unused code from the example Scheme interpreter.

59adbdab1c Avoid warnings under gcc: 
* Use <errno.h> instead of "extern int errno;".
* Can't cast function pointer to object pointer.
* GCC's dataflow analysis wrongly thinks "end" can be used uninitialized.

d984d32588 New constructor make_bool avoids boilerplate. 
Hash function takes a length so that it (1) it can support strings containing NULs; (2) it doesn't have to check for NULs so runs a bit faster; and (3) it performs OK on addresses (which often contain zero bytes).
Hash tables have hash and comparison functions.
Implement string=?, make-eqv-hashtable and make-hashtable.
