Exploit the fast-path for allocation of array with initial element 0 by changing
...
new-sequence on arrays, the vector constructor, and resize-array, called when
growing vectors, to fill arrays with 0 instead of f. user code never observes the
initial value in these situations anyway. small speedup on bootstrap

Tweak string representation; high bit indicates if character has high bits in aux vector. Avoids memory access in common case. Split set-string-nth into two primitives; set-string-nth-fast is open-coded by optimizing compiler. 13% improvement on reverse-complement

New calling convention for VM primitives:
...
instead of the Factor side passing the stack pointer as the first parameter, and having the VM save it to stack_chain->top, we instead have the Factor side save it. Eliminates a lot of crud in the VM

Word constructor was not invoking relocation on the profiled block, so words constructed while profiling was on could not be executed. This prevented profiling of PEGs

Tuple layouts are now arrays, instead of built-in types. The superclass
...
array is now part of the tuple layout object itself, and class hashcodes
are stored alongside class words there. This removes 2 indirections when
reading a superclass, and 3 when reading a superclass hashcode.
