56a5573881 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).

10999f8ba8 If mps_key_spare_commit_limit and mps_key_spare are both given, then the latter takes precedence. 
If MPS_KEY_SPARE_COMMIT_LIMIT has a value greater than the commit limit, clamp the spare commit limit to 1.0.
Add smoke test coverage of MPS_KEY_SPARE, mps_arena_spare, and mps_arena_spare_set.
Document the deprecation of MPS_KEY_SPARE_COMMIT_LIMIT.
