  Log Message:
  -----------
  Move snek_null_mark_move to snek_string_mark_move, eliminate snek_null_size

These functions were shared with snek_builtins type, but the memory system now
just skips builtin objects early.

  Shrink some memory management code

A bit of CSE, plus letting the target do unaligned reads and writes.

  More memory management shrinking

Place snek_mem_t contents in snek_mems instead of just having pointers.
Un-inline snek_move_addr and snek_mark_addr in snek_poly_move/snek_poly_mark.
Move memmove for string references from snek-code.c to snek-memory.c.

  Check for snek_abort right after instruction execution

This avoids doing any instruction final steps on partially computed
data, and also avoids needing two checks for abort.

  Log Message:
  -----------
  Make sure only top-level simple statements get printed output

There aren't void values, so as a proxy, only simple top-level
statements get values printed. Making sure that happens is tricky,
this time snek_print_val is set to snek_print_vals before parsing a
single statement, and false if that statement is compound or
empty.

  Log Message:
  -----------
  Handle parse error recovery (skipping to NL) in snek_parse.

This moves the skip_to_nl code out of the lexer wrapper and into
snek_parse, eliminating the lex wrapper and avoiding a bunch of
variable frobbing.

  Refactor grammar actions to shrink code.

Clean up if/elif/else actions to use the same names for matching

Remove 'else-stat' non-terminal -- it had only one production and was
used in only one place.

  Log Message:
  -----------
  Create new (smaller) type for parse value stack elements

The parse value stack only needs to hold a few types, not all of the
possible types returned by the lexer. Creating a custom type makes
each element smaller as well as shrinking the code needed to deal with
managing the stack.
