Replace repetitive C code in "gc.c" and "vfasl.c" with an implementation using a little "Parenthe-C" language, which is a somewhat declarative description of object tracing. From that descrition, we generate different kinds of tracing functions, such as the copy function or the sweep function. The little language is still bascially C, just with parentheses and parameterization that is much better than trying to use the C preprocessor. (The "mkgc.ss" file includes the compiler from Parenthe-C to C.) Besides replacing existing code, we also generate a new traversal to implement `compute-object-sizes`. Finally, the GC can now perform a fused `collect` and `compute-object-sizes` in a single traversal. Also improve the way that locked objects are detected during GC. This can make a significant difference (on the order of 10-20% for a full collection) when locked objects are long-lived. original commit: de1f5c41d729ac75822a1f1e633ec6d042c883dc
