compiler.cfg.*: new word for consuming deques slurp/replenish-deque
...
most uses of slurp-deque processes one item and pushes a sequence of
items to continue working with. it can be formalized into a
slurp/replenish-deque combinator which also reduces the amount of
variables you need to use

compiler.cfg.dataflow-analysis: generic for configuring the "block skipping"
...
To accurately record uninitialized/overinitialized stack locations,
kill blocks needs to be analyzed. Now you can make it so by overriding
ignore-block?.

Refactor the lexer/parser to expose friendlier words for scanning tokens. The preferred top-level words now throw an exception on EOF.
...
CREATE -> scan-new
CREATE-CLASS -> scan-new-class
CREATE-WORD -> scan-new-word
CREATE-GENERIC -> scan-new-generic
scan -> (scan-token)
scan-token now throws on eof
(scan-word) returns word/number/f
scan-word now throws on eof
scan-word-name expects a non-number
Fixes #183 .
Fixes #209 .

compiler.cfg: new system to track when results of analyses need to be recomputed (reverse post order, linear order, predecessors, dominance, loops). Passes can now call needs-predecessors, needs-dominance, needs-loops at the beginning, and cfg-changed, predecessors-changd at the end. Linearization order now takes loop nesting into account, and linear scan now uses linearization order instead of RPO.

compiler.cfg: Major restructuring -- do not compute liveness before local optimization, and instead change local optimizations to be more permissive of undefined values. Now, liveness is only computed once, after phi elimination and before register allocation. This means liveness analysis does not need to take phi nodes into account and can now use the new compiler.cfg.dataflow-analysis framework
