typecase: merge with etypecase, handle t differnetly.
* stdlib/type.tl (sys:typecase-expander): New function, formed
from body of typecase. Bad clause syntax now handled with
compile-error rather than (throwf 'eval-error). The t symbol
is handled specially: it turns into a t conditon in the
resulting cond rather than a typep test. The compiler will
nicely eliminate dead code after that. Now etypecase is handled
here also: if we are expanding etypecase, we just emit the
extra clause.
(typecase, etypecase): Reduced to sys:typecase-expander calls.
* tests/012/typecase.tl: New file.
* tests/012/compile.tl: Add type.tl to list of compile-tested
files.
